Question

5 (-3+x) - 4 (2+x)= 3 (-2x +1) +2

Answer 1

$5( - 3 + x) - 4(2 + x) = 3( - 2x + 1) + 2$
remova os Parênteses

$- 15 + 5x - 8 - 4x = - 6x + 3 + 2$
calcule a soma

$- 23 + x = - 6x + 5$
mova os termos

$x + 6x = 5 + 23$
calcule a soma

$7x = 28$
divida ambos por 7

$x = 4$

Answer 2

5(-3+x)-4(2+x)=3(-2x+1)+2
-15 +5x-8-4x=-6x+3+2
5x-4x +6=5+15+8
7x=28
x=28/7
x=4
