Question

resolva as equacoes x + 8 = 10
6x - 10 = 2x + 14 6x = 2x + 28 2x - 2 - 7 = 16 7x - 1 = 13

Answer 1

Explicação passo-a-passo:

x + 8 = 10 6x - 10 = 2x + 14

x= 10 - 8 6x - 2x = 14 + 10

x = 2 4x = 24

x = 24/4

x = 6

6x = 2x + 28 2x - 2 - 7 =16

6x - 2x = 28 2x = 16 +7 + 2

4x = 28 2x = 25

x = 28/4 x = 25/2

x = 7

7x - 1 = 13

7x = 13 + 1

7x = 14

x = 14/7

x = 2
