Resposta:

1)

a) x=6

b)x=2

c)x=-12

d)x=25/7

2) x=6

Explicação passo-a-passo:

Oi.

1)

a)3(x+3)-5=22

3x+9-5=22

3x=13+5

3x=18

x=18/3=6

b)4(2x-1)=3(x+2)

8x-4=3x+6

8x-3x=6+4

5x=10

x=10/5=2

c)3(x+2)-1=2(x+3)-7

3x+6-1=2x+6-7

3x-2x=-7-6+1

x=-12

d)5(2x-1)=3(x+10)

10x-5=3x+30

10x-3x=30-5

7x=25

x=25/7

2)4(x+3)-x=24+x

4x+13-x=24+x

4x-2x=24-12

2x=12

x=12/2=6

Desculpa se eu errei algo.
