- 1.68 + 0.6x = 12x
12x - 0.6x = -1.68
11.4x = -1.68
x = - 0.147

-0.2(8.4 - 3x)=12x Multiply through the left to get
-1.68+.6x=12x Subtract .6x from both sides to get
-1.68 = 11.4x Divide both sides by 11.4 to get
-.147368421=x

-0.2(8.4 - 3x)=12x divide both sides by -0.2
8.4-3x=-60x add 60x to each side
57x+8.4=0 subtract 8.4 from each side
57x=8.4
19x=2.8
x=0.147

-0.2(8.4-3x) =12x
-1.68 + 0.6x =12x
-1.68 = 12x -0.6x
-1.68 = 11.4x
x = -1.68 / 11.4
x = -0.147

8.4 - 3x = 12x/-.2
8.4 - 3x + 60x = 0
57x = -8.4
x = -0.14

-1.68 + 0.6x = 12x
-1.68 = 12x - 0.6x
-1.68 = 11.4x
-1.68/11.4 = x
x = -0.147368421
