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
i cant read what 8 is but just repeat
