Question

alguem sabe ? 5.(x-4)=-3+9.(x-1)

Answer 1

5(x - 4)= - 3 + 9(x - 1)

5x - 20= - 3 + 9x - 9

5x - 9x= - 3 - 9 + 20

- 4x= 8>> .(-1)

4x= - 8

x= - 8/4

x= - 2

Answer 2

Explicação passo-a-passo:

$5(x - 4) = - 3 + 9(x - 1)$

$5x - 20 = -3 + 9x - 9$

$5x - 20 = 9x - 12$

$5x - 9x = - 12 + 20$

$- 4x = 8$

$x = \frac{ 8}{ - 4}$

$x = -2$
