a) 4x + 3 = 11 4x = 11 - 3 = 8 x = 8/4 = 2
b) 2x - 9 = 12 2x = 12 + 9 = 21 x = 21 / 2 = 10,5
c) 6x - 2x +4 = 3 4x + 4 = 3 4x = 3 - 4 4x = 3 - 4 = -1 x = -1/4
d) -3x + 6 = -12 -3x = -12 - 6 -3x = -18 x = 18/3 = 6
e) -12 - 5x = 3 -5x = 3 + 12 -5x = 15 x = -3
f) 6x - 8x - 3 = 7 -2x = 7 + 3 x = -5
g) 7x - -2 - 3x = 14 4x = 14 + 2 x = 4
