Question

1x - 4 = 2 - 2x
1x + 8 = 15 - 2x
x - 10 = 5
14x - 4 = 2 - 4x
x + 3 = 1 - 2x

Answer 1

Resposta:

1x - 4 = 2 - 2x

1x + 2x = 2 + 4

3x = 6

x = 6 ÷ 3

x = 2

1x + 8 = 15 - 2x

1x + 2x = 15 - 8

3x = 7

x = 7 ÷ 3

x = 2,33..

x - 10 = 5

x = 5 + 10

x = 15

14x - 4 = 2 - 4x

14x + 4x = 2 + 4

18x = 6

x = 18 ÷ 6

x = 1/3

x + 3 = 1 - 2x

x + 2x = 1 - 3

3x = -2

x= -2/3
