Question

-3(x-5)-2(2x+1)= -8
Obs: passo a passo

Answer 1

Boa tardee

________________________________

$- 3(x - 5) - 2(2x + 1) = - 8 \\ - 3x + 15 - 4x - 2 = - 8 \\ (- 3x) - 4x = - 8 - 15 + 2 \\ - 7x = - 21( - 1) \\ 7x = 21 \\ x = \frac{21}{7} \\ x = 3$

Bons estudos =)

Answer 2

-3(x-5)-2(2x+1)=-8

-3x+15-4x-2=-8

-3x-4x+15-2+8=0

-7x+21=0

-7x=-21

7x=21

x=21÷7

x=3
