4-37.

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

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

Hint 1(a):
Combine like terms.
$9a-3=4a-3$
Hint 2(a):
Get the variable on a side by itself.
$5a=0$

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

Hint (b):
Use a generic rectangle to simplify each side.
Answer (b):
$m=-2$

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

Hint (c):
Get $x$ on a side by itself and then multiply both sides by $2$ .

$4t-2+t^2=6+t^2$

Hint (d):
Start by subtracting $t^2$ from both sides of the equation.
