Question

x+x+2x+2+2x+2=x-1+x-1+3x+1+3x+1

Answer 1

x + x + 2x + 2 + 2x + 2 = x - 1 + x - 1 + 3x + 1 + 3x + 1

4x + 2 + 2x + 2 = x + x + 3x + 3x - 1 - 1 + 1 + 1

4x + 2x + 2 + 2 = 2x + 6x - 2 + 2

6x + 4 = 8x

4 = 8x - 6x

4 = 2x

2x = 4

x = 4/2

x = 2

Answer 2

x + x + 2x +2 + 2x + 2 = x -1 +x -1 + 3x + 1 + 3x +1
6x +4 = 8x 
6x - 8x = -4
-2x= -4 (-1)
x = 4/2
x=2
