4-37.

Solve each equation for the variable. Check your solutions, if possible. Homework Help ✎

1. $8 a + a - 3 = 6 a - 2 a - 3$

• Combine like terms.

9a − 3 = 4a − 3

Get the variable on a side by itself.

5a = 0

1. $( m + 2 ) ( m + 3 ) = ( m + 2 ) ( m - 2 )$

• Use a generic rectangle to simplify each side.

m = −2

1. $\frac { x } { 2 } + 1 = 6$

• Get x on a side by itself and then multiply both sides by 2.

1. $4 t - 2 + t ^ { 2 } = 6 + t ^ { 2 }$

• Start by subtracting t 2 from both sides of the equation.
