Solve the following equations. you will need to show your work in order to receive full credit. 4x – 8 = 32 2(x – 5) = -20

Hello from MrBillDoesMath!

  x =  10 for 4x - 8 = 32

               x = -5  for 2(x-5) = -20

Discussion:

4x - 8 = 32    (*)

Add 8 to both sides:

4x - 8 + 8 = 32 + 8 =>

4x = 40 =>

x = 10

2(x-5) = 2x - 2(5)  =>

2x - 10 = -20 (**)

Add 10 to each side of (**):

2x - 10 + 10 = -20 + 10 =>

2x = -10

x = -5

Thank you,

MrB
