x + 2x - x + 7 = 4x - x + 2 Clean this up.
2x + 7 = 3x + 2
Subtract 2x from both sides.
7 = x + 2
Now subtract 2 from both sides.
5 = x ◄
Check
5 + 2(5) - 5 + 7 = 4(5) - 5 + 2
5 + 10 - 5 + 7 = 20 - 5 + 2
15 - 5 + 7 = 15 + 2
10 + 7 = 17 ■

4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
2x = 4x + 3 -2x = 3 x = -3 / 2
X equals 2 :)
(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
If: 1-2x-5 = 4x+2 Then: -2x-4x = 2-1+5 And: -6x = 6 So: x = -1
