Answer 1

Hello from MrBillDoesMath!

Answer:   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
