3x + 7 = 2x +1
7 – 2x = 5x + 28
x = 8 – 2x
8x – 5 = 9x – 5
6x + 2x - 10 = 3x + 5
3( x + 2) – x = 2
2(x + 4) – 1 = 5x + 2
4 + 2(x +1) = 6x +2
8 – 2x + 7(x – 1) = 4x +1
5x – 3(x +1) = 2x -3
11 -3x = 5x -4(2x +1)
7 = 3(x+2) + 4( x-1)
3 – 2x = 1 – (-2 + x)
2(x+2) – 3(x -1) +8 = 3x -1
4x – 3(x +7) – 5x + 2(x -1) = 9
5x (x -2) – x (5x -2) = - 4
6x (3 – 2x) = 5 + 4x(7- 3x)
