Bài toán 5 : Tìm x, biết.
a.      2(x – 5) – 3(x + 7) = 14
b.     5(x – 6) – 2(x + 3) = 12
c.      3(x – 4) – (8 – x) = 12
d.     -7(3x – 5) + 2(7x – 14) = 28
e.      5(3 – 2x) + 5(x – 4) = 6 – 4x
f.       -5(2 – x) + 4(x – 3)  = 10x – 15
g.     2(4x – 8) – 7(3 + x) = |-4|(3 – 2)
h.     8(x – |-7|) – 6(x – 2) = |-8|.6 – 50
k.       -7(5 – x) – 2(x – 10) = 15
l.        4(x – 1) – 3(x – 2) = -|-5|
m.      -4(x + 1) + 89x – 3) = 24

n.       5(x – 30 – 2(x + 6) = 9
o.       -3(x – 5) + 6(x + 2) = 9
p.       7(x – 9) – 5(6 – x) = – 6 + 11x
q.       10(x – 7) – 8(x + 5) = 6.(-5) + 24
