However, if you multiply both sides of an equation by \(6\), you obtain an equivalent equation. 2) the quotient of 15 and a number.11 pages. When no sign precedes the term, it is understood to be positive. Linear equations and inequalities worksheet | Math Preparation In general, given algebraic expressions \(A\) and \(B\), where \(c\) is a positive nonzero real number, we have the following properties of inequalities140: If \(A}\:\color{Cerulean}{-c}\color{Cerulean}\color{Black}{B}\), If \(A}\frac{\color{Black}{B}}{\color{Cerulean}{-c}}\). The problems are organized as follows:#1-3: Solve by Graphing (I suggest providing graphs or graph paper for your students)#4-6: Solve using Substitution#7-12: Solve using Elimination (addition, subtraction, + multiplication)#13-15: Graphing Linear Inequalities#16-18: Graphing Systems of Linear InequalitiesThis works great as an end of unit review!Preview this set HERE!Th. Given algebraic expressions \(A\) and \(B\), where \(c\) is a nonzero number: Multiplying or dividing both sides of an equation by \(0\) is carefully avoided. 2 0 obj Show each step of your work! endobj @d]J].a(PeJjsUlO^%5_IX=O5;s.7 Graph your solution. We can also represent inequalities using interval notation. We use these properties to obtain an equivalent inequality141, one with the same solution set, where the variable is isolated. 2. \(\begin{array} { c } { - 2 y - 3 \color{Cerulean}{- 5 y}\color{Black}{ =} 5 y + 11 \color{Cerulean}{- 5 y} } \\ { - 7 y - 3 = 11 } \end{array}\). Solve: \(\frac { 1 } { 3 } x + \frac { 1 } { 5 } = \frac { 1 } { 5 } x - 1\). \(\begin{array} { c } { - 2 ( 4 x - 5 ) < 9 - 2 ( x - 2 ) } \\ { - 8 x + 10 < 9 - 2 x + 4 } \\ { - 8 x + 10 < 13 - 2 x } \\ { - 6 x < 3 } \\ { \frac { - 6 x } { \color{Cerulean}{- 6} } \color{OliveGreen}{>} \frac { \color{Black}{3} } { \color{Cerulean}{- 6} } }\color{Cerulean}{Reverse\:the\:inequality.} Explore math program Dividing by \(5\) results in a false statement.

Solving Linear Equations And Inequalities Worksheets & Teaching Multi Step Inequalities Modeling Teaching Resources | TPT \(\begin{aligned} \color{Cerulean}{15}\color{Black}{ \cdot} \left( \frac { 1 } { 3 } x + \frac { 1 } { 5 } \right) & = \color{Cerulean}{15}\color{Black}{ \cdot} \left( \frac { 1 } { 5 } x - 1 \right) \quad \color{Cerulean}{Multiply\: both\: sides\: by\: 15.} Figure \(\PageIndex{2}\) shows both the number line and the interval notation. To obtain equivalent equations, use the following properties of equality133. Here we point out that \(a\) is equivalent to \(1a\); therefore, we choose to divide both sides of the equation by \(1\). The barcode scanner beeped as I passed it over the items in my cart. You can choose from SEVEN basic types of equations, ranging from simple to complex, explained below (such as one-step equations, variable on both sides, or having to use the distributive property).

In this text we will choose to present answers using interval notation. >cSs~-kTAPJl8rM <>heL When \(6\) is subtracted from twice the sum of a number and \(8\) the result is \(5\). y=0x + 5. : 1012141618 9) n > -5: -6-4-202 10) x -1: -4-20246 11) No solution. Solve linear inequalities and express the solutions graphically on a number line and in interval notation. It is important to know that this technique only works for equations. In this sense, we say that solutions satisfy the equation.. \(\begin{aligned} - 7 y - 3 & = 11 \quad\color{Cerulean}{Add\: 3\: to\: both\: sides.} Recall that when evaluating expressions, it is a good practice to first replace all variables with parentheses, and then substitute the appropriate values. We then shade in all the numbers to the left of one, to show that all numbers less than one are solutions (Figure \(\PageIndex{3}\)). Solve: \(\frac { 2 } { 3 } x + \frac { 1 } { 2 } = - \frac { 5 } { 6 }\).
