Question

4x-14=8x-2
9x+9+3x=15
5x+4=3x-2x+4

Answer 1

Resposta:

a)4x-7=8x-2

4x-8x=-2+7

-4x=5

-x=5/4(-1)

x=-5/4

B)  9x+3x=15-9

12x=6

x=6/12÷6

x=1/2

C) 5x+4=3x-2x+4

5x-3x+2x=4-4

4x=0

x=

x=0

Answer 2

Resposta:

Explicação passo a passo:

A)

4x-14=8x-2

- 14 + 2 = 8x - 4x

- 12 = 4x

4x = - 12

x = - 12/4

x = - 3

B)

9x+9+3x=15

12x + 9 = 15

12x = 15 - 9

12x = 6 (:6)

2x = 1

x = 1/2

C)

5x+4=3x-2x+4

5x + 4 = x + 4

5x - x = 4 - 4

4x = 0

x = 0/4

x = 0
