4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11

2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
2x = 4x + 3 -2x = 3 x = -3 / 2
4x - 5 + 2x = 376x - 5 = 376x = 37 + 56x = 42x = 42 / 6x = 7
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11

2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
2x + 2 = 4x -1 2x = 3 x = 1.5
2x = 4x + 3 -2x = 3 x = -3 / 2
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.
2x + 33 = 4x + 11 -11 -11 2x + 22 = 4x -2x -2x 22 = 4x Divide each side by 4 x = 5.5
2x + 2x + 146 + 26 = 172 4x + 172 = 172 4x = 0 x = 0
2x-3=4x+9 -2x-12=0 2x=-12 x=-6
