Question

qual a resposta? a) 4x + 10 = x-5
b) 5x - 4 + 2x = 10
c) 6x-24 = 0​

Answer 1

Resposta:

a) 4 + 1 0 = − 5

4 + 0 − 1 0 = − 5 − 1 0

= − 5

b) 5 − 4 + 2 = 1 0

7 − 4 = 1 0

x= 2

c) 6 − 2 4 = 0

6 − 2 4 + 2 4 = 0 + 2 4

x = 4

Answer 2

Olá!

A) 4x + 10 = x - 5

4x + 10 - 10 = x - 5 - 10

4x = x - 15

4x - x = x - 15 - x

3x = -15

x = -15 / 3

x = -5

B) 5x - 4 + 2x = 10

5x + 2x = 10 + 4

7x = 14

x = 14 / 7

x = 2

C) 6x - 24 = 0

6x = 24

x = 24 / 6

x = 4

Espero ter ajudado (:
