8-9.
1. Solve each equation for the indicated variable. Homework Help ✎

1. y = 3x + 2 (for x)

2. a = (for b)

3. 7 = (for x)

4. g = at2 (for t2)

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).

$x=\frac{2y}{3}+14$

$t^2=\frac{2g}{a}$
