In order to solve an equation, we must get variables on side of an equation, and constants on the opposite side.

• True

• False

9 + 2a = -3 - 4a

• a = -2

• a = 2

• a = 5

• a = -1

2a + 4 = 7 + a

• a = 1

• a = -3

• a = -1

• a = 3

Solve for y:

 $\frac{4}{3}y\ +1=-14$  

•  $y=-21$  

•  $y=-12$  

•  $y=-16$  

•  $y=4$  

Solve by clearing the fractions first:

• x = -4
• x = 4
• x = 3
• x = -12
