Evaluate 6x 4 when x = 2. Solving equations and inequality worksheets is helpful as they are used to compare numbers and determine the range or ranges of values that satisfy the conditions of a given variable. Solve: $- \frac { 1 } { 2 } ( 10 x - 2 ) + 3 = 7 ( 1 - 2 x )$. To solve problems using algebra, first translate the wording of the problem into mathematical statements that describe the relationships between the given information and the unknowns. Show each step of your work! It does not matter on which side we choose to isolate the variable because the symmetric property134 states that $4 = y$ is equivalent to $y = 4$. (Note that this will open a different textbook in a new window. \\ x & = 3 \end{aligned}\). \(\begin{array} { c } { \frac { 1 } { 2 } x - 2 \geq \frac { 1 } { 2 } \left( \frac { 7 } { 4 } x - 9 \right) + 1 } \\ { \frac { 1 } { 2 } x - 2 \geq \frac { 7 } { 8 } x - \frac { 9 } { 2 } + 1 } \\ { \frac { 1 } { 2 } x - \frac { 7 } { 8 } x \geq - \frac { 7 } { 2 } + 2 } \\ { - \frac { 3 } { 8 } x \geq - \frac { 3 } { 2 } } \\ { \left( \color{Cerulean}{- \frac { 8 } { 3 }} \right) \left(\color{Black}{ - \frac { 3 } { 8 } x} \right) \leq \left( \color{Cerulean}{- \frac { 8 } { 3 }} \right) \left( \color{Black}{-} \frac { 3 } { 2 } \right) \quad \color{Cerulean} { Reverse\: the\: inequality. } 2.1E: Exercises.

It is helpful to take a minute and choose a few values in and out of the solution set, substitute them into the original inequality, and then verify the results. This leads to the following new rule: when multiplying or dividing by a negative number, reverse the inequality. In addition to being easy to use, the linear equations and inequalities worksheets have answer manuals that contain the solutions to all problems given in the sheet. Sheila J. Waggoner and Jennifer A.

Next, isolate the variable using the equality property of multiplication or division. To understand why we included the parentheses in the set up, you must study the structure of the following two sentences and their translations: The key was to focus on the phrase twice the sum, this prompted us to group the sum within parentheses and then multiply by $2$. We can express this solution in two ways: using set notation and interval notation.
