Question

Como resolver isso
-2(x+5 )= (x-8)

Answer 1

-2(x+5 )= (x-8)
-2x - 10 = x - 8
-2x - x = - 8 + 10
-3x= 2 (-1)
3x= -2
x= $\frac{-2}{3}$

8(x-2) = 5(x+7)
8x - 16 = 5x + 35
8x - 5x = 35 + 16
3x = 51
x= $\frac{51}{3}$
x= 17

X+2-5= -3x+15
x - 3 = -3x + 15
x + 4x = 15 + 3
5x= 18
x= $\frac{18}{5}$
