6-8.

Solve each equation for the indicated variable. Homework Help ✎

1. $y = 3 x + 2 ( \text { for } x )$

1. $a = \frac { b } { c } ( \text { for } b )$

• Isolate the term with the x on one side of the equation.

• $x=\frac{y-2}{3}$

• Multiply both sides by c
(Multiplication Property of Equality).

1. $\frac { x } { 2 } - 7 = \frac { y } { 3 } ( \text { for } x )$

1. $g = \frac { 1 } { 2 } a t ^ { 2 } ( \text { for } t ^ { 2 } )$

• $x=\frac{2y}{3}+14$

• $t^2=\frac{2g}{a}$
