Question

a) 10x + 2 = 4x b) 13x - 2 = 7x + 4 c) 4x = 44 d) 2x . 3 = 12

Answer 1

Resposta:

a) -1/3

b) 6/5

c) 11

d) 2

Explicação passo a passo:

a) 10x + 2 = 4x

10x - 4x = -2

6x = -2

x = -2/6

x = -1/3

b) 13x -2 = 7x + 4

13x - 7x = 4 + 2

5x = 6

x = 6/5

c) 4x = 44

x = 44/4

x = 11

d) 2x . 3 = 12

2x = 12 /3

x = 4/2

x = 2
