1) x + 2 = -x + 14; 3) 45 - 2x = 3x + 5; 5) 4x - 7 = 2x - 3;
2х = 12 -5х = -40 2х = 4
х = 6 х = 8 х = 2
2) 2x - 3 = x + 1; 4) 9x - 32 = 2 + 5x; 6) 8x - 3 = x + 11.
х = 4 4х =34 7х = 14
х = 8,5 х = 2

1) 4x + 3 = x - 9; 3) 7x + 3 = 3x + 27; 5) 42 - x = 2x + 9;
3х = -12 4х = 24 -3х = -33
х = -4 х =6 х = 11
2) 2x - 19 = 8 - x; 4) 3x - 7 = 2x + 3; 6) 20 + 3x = 4 - X.
3х = 27 х = 10 4х = -16
