Question

5. (x + 2) -8.x = 5x + 10 - 8x = -3x + 10
auguem sabe o resultado dessa conta??? pfvr ;-;​

Answer 1

Resposta:

(x + 2) -8.x = 5x

$5\left(x+2\right)-8x=5x\\-3x+10=5x\\-3x+10-10=5x-10\\-3x=5x-10\\-3x-5x=5x-10-5x\\-8x=-10\\\frac{-8x}{8} = \frac{-10}{-8} \\x= \frac{5}{4}$

10 - 8x = -3x + 10

$10-8x-10=-3x+10-10\\-8x=-3x\\-8x+3x=-3x+3x\\-5x=0\\\frac{-5x}{5} = \frac{0}{-5} \\x=0$
