(8 - x) = x + 3(4 - x) - x

Answer 1

x−12(8−x)=x+3(4−x)−x

x+(−12)(8)+(−12)(−x)=x+(3)(4)+(3)(−x)+−x

x+−96+12x=x+12+−3x+−x

(x+12x)+(−96)=(x+−3x+−x)+(12)

13x+−96=−3x+12

13x−96=−3x+12

13x−96+3x=−3x+12+3x

16x−96=12

16x−96+96=12+96

16x=108

16x/16=108/16

x=27/4

Answer is x=27/4

Answer 2

8-x=x+3(4-x)-x
8-x=x+12-3x-x
8-x=x+12-4x
8-x=-3x+12
-x=-3x+4
2x=4
x=2
