Step-by-step explanation:

<3

for these problems you just want to set whats given to the equations

5. 63 = -7x

so you solve this like any other equation, divide both sides by -7

your answer to question 5 is x = -9

6. 18 = 6x - 12

you will add your 12 over

30 = 6x

x = 5

7. -4 = 1/2x - 3

-1 = 1/2x

x = -2
