Question

Resolva:

2(x+6)=34
4x-8=2x+20
9x-×=48

Answer 1

Explicação passo-a-passo:

2x+12=34

2x=34-12

2x=22

x=22/2

x=11

4x-8=2x+20

4x-2x=20+8

2x=28

x=28/2

x=14

9x-x=48

8x=48

x=48/8

x=6

Respostas: x=11

x=14

x=6

Answer 2

Olá!!  :)

$\sf PRIMEIRA: \\\\ \\ 2(x + 6) = 34 \\\\ 2x + 12 = 34 \\\\ 2x = 34 - 12 \\\\ 2x = 22 \\\\ x = \frac{22}{2} \\\\ x = 11 \\\\\\\\ SEGUNDA: \\\\ \\ 4x - 8 = 2x + 20 \\\\ 4x - 2x = 20 + 8 \\\\ 2x = 28 \\\\ x = \frac{28}{2} \\\\ x = 14 \\\\\\\\ TERCEIRA: \\\\ \\ 9x - x = 48 \\\\ 8x = 48 \\\\ x = \frac{48}{8} \\\\ x = 6$

Espero ter ajudado, bons estudos!!  :)
