Question

Is this right? Solve 12x + 2(5 – 2x) = 2x – 6(7 – x). Please show all of your work.
12x+2(5-2x) = 2x-6(7-x)
12x+10-4x = 2x-36-6x
12x+4x-(-2x)+6x=36-10
16x= 26
16x/16= 26/16
x=1 10/16
x = 1 5/8 simplest form

Answer 7

12x+2(5-2x) = 2x-6(7-x)
12x+10-4x = 2x-42-6x
12x+4x-(-2x)+6x=-42-10
16x= -36
16x/16= -36/16
x= -2 4/16
x = -2 1/4 simplest form
