7x-3=11


8x-10=14

ajuda por favor​

Answer 1

Resposta:

4, 2, 3

Explicação passo-a-passo:

a) 6x + 18 = 42

6x = 42 - 18

6x = 24

x = 4

b) 7x -3 = 11

7x = 11 + 3

7x = 14

x = 2

c) 8x -10 = 14

8x = 14 +10

8x = 24

x = 3

Answer 2

6x + 18 = 42

6x = 42 - 18

6x = 24

x = 24 ÷ 6

× = 4

7x - 3 = 11

7x = 11 + 3

7x = 14

x = 14 ÷ 7

x = 2

8x - 10 = 14

8x = 14 + 10

8x = 24

x = 24 ÷ 8

x = 3
