Resposta:

a)

$3 x+ 8 = 32 \\ 3x = 32 - 8 \\ 3x = 24 \\ x = 24 \div 3 \\ x = 8$

b)

$6x = 48 \\ x = 48 \div 6 \\ x = 8$

c)

$2x - 12 = 40 \\ 2x = 40 + 12 \\ 2x = 52 \\ x = 52 \div 2 \\ x = 26$

d)

$x - 15 = 16 \\ x = 16 + 15 \\ x = 31$

Answer 2

a)3x+8=32

3x=32-8

3x=24

x=8

b)6x=48

x=8

c)2x-12=40

2x=40+12

2x=52

x=26

d)x-15=16

x=16+15

x=31
