Question

a) x/2 +8= 13

b) 6x +18= 2x+38​

Answer 1

Resposta:

a) x ÷ 2 + 8 = 13

x ÷ 2 = 13 - 8

x ÷ 2 = 5

x = 5 × 2

x = 10

b) 6x + 18 = 2x + 38

6x - 2x = 38 - 18

4x = 20

x = 20 ÷ 4

x = 5

Answer 2

A) x\2+8=13

x\2=13-8

x\2=5

x=5.2

x=10

B) 6x+18=2x+38

6x-2x=38-18

5x=20

x=20\5

x=5
