4.1)

Solve the equations:

a): $2 x + 3 - x = 7 x + 17$
b): $4 x + 21 = x - 4 x + 3$
c): $11 + x - 4 x = - 2 x + 13 - 2$
d): $11 x - 4 x + 5 = - 5 x + 12$
e): $2 x - 8 + 5 x = 3 x + 32$
f): $20 x - 6 - 8 x = 6 x + 5 + 7 x$
g): $34 x - 12 x - 42 = 32 x - 21 + 41$
h): $2 x + 21 - 5 x = 21 + 52 - 11 x$
i): $22 x - 11 = 11 x + 22$

c): $11 + x - 4 x = - 2 x + 13 - 2$
d): $11 x - 4 x + 5 = - 5 x + 12$
e): $2 x - 8 + 5 x = 3 x + 32$
f): $20 x - 6 - 8 x = 6 x + 5 + 7 x$
g): $34 x - 12 x - 42 = 32 x - 21 + 41$
h): $2 x + 21 - 5 x = 21 + 52 - 11 x$
i): $22 x - 11 = 11 x + 22$
j): $32 x - 23 = 2 x + 1 - 3 x$
