5.1)

Solve the equations:

a): $\frac{3 + x}{4} - 5 = 2 x - 3$
b): $\frac{2 + 2 x}{3} + 4 = \frac{x - 3}{2} - 7$
c): $\frac{x}{7} - 20 + x = \frac{x + 2}{3} + 11$
d): $\frac{21 + 2 x}{5} + 12 = 22 - \frac{2 x}{3}$
e): $\frac{3 x}{8} + 13 - 2 x = - 12 + \frac{3 x}{16}$
f): $23 - 3 x + \frac{4 x - 1}{3} = 9 + \frac{21 x}{4}$

a): $\frac{3 + x}{4} - 5 = 2 x - 3$
b): $\frac{2 + 2 x}{3} + 4 = \frac{x - 3}{2} - 7$
c): $\frac{x}{7} - 20 + x = \frac{x + 2}{3} + 11$
d): $\frac{21 + 2 x}{5} + 12 = 22 - \frac{2 x}{3}$
e): $\frac{3 x}{8} + 13 - 2 x = - 12 + \frac{3 x}{16}$
f): $23 - 3 x + \frac{4 x - 1}{3} = 9 + \frac{21 x}{4}$

5.2)

Solve the equations:

a): $x (7 - 5) = 4$
b): $2 (x - 1) = 6$
c): $3 (x + x) = 12$
d): $3 (\frac{1}{2} - x) = 2 (x + 1)$
e): $4 (2 x + 5) = 5 x + 38$
f): $12 (\frac{x}{3} + \frac{2 x}{4}) = - 5 (3 x - 20)$
g): $\frac{2}{5} + 10 x - 1 = 3 (3 x - 2)$
h): $6 x (4 - \frac{2}{3}) = 9 (3 x + 7)$

a): $x (7 - 5) = 4$
b): $2 (x - 1) = 6$
c): $3 (x + x) = 12$
d): $3 (\frac{1}{2} - x) = 2 (x + 1)$
e): $4 (2 x + 5) = 5 x + 38$
f): $12 (\frac{x}{3} + \frac{2 x}{4}) = - 5 (3 x - 20)$
g): $\frac{2}{5} + 10 x - 1 = 3 (3 x - 2)$
h): $6 x (4 - \frac{2}{3}) = 9 (3 x + 7)$
