Question

Resolva as equações A)2x+28=48 B)1+2x=3 C)8x=2x+18 D)6x-2=4x+10

Answer 1

A) 10

B) 1

C) 3

D) 6

Explicação passo-a-passo:

A)2x + 28 = 48

2x = 48 - 28

2x = 20

x = 20/2

x = 10

_____________

B)1 + 2x = 3

2x + 1 = 3

2x = 3 - 1

2x = 2

x = 2/2

x = 1

____________

C)8x = 2x + 18

8x - 2x = 18

6x = 18

x = 18/6

x = 3

____________

D)6x - 2 = 4x + 10

6x - 2 - 4x = 10

2x - 2 = 10

2x = 10 + 2

2x = 12

x = 12/2

x = 6
