• 10x + 30 + 13x + 20

• 63x

• 23x + 50

• 50x + 23

x + 2.5 = - 2.5

• -5

• 5

• 5.5

• -5.5

- $\frac{2}{3}$  m = -12

•  $\frac{36}{2}$  

• -18

• - $\frac{36}{2}$  

• 18

Simplify the following Expression

6m - 5q + -12mq - 12m

• 6m - 5q + -12mq

• -6m - 5q + -12mq

• -6m - 17mq

• -18m - 5q - 12mq
