Question

A) x-3.(6-2x)=-5.(3-x)

b) 10+8.(x+4)=-2x

COM CALCULO

Answer 1

$a)\ x-3.(6-2x)=-5.(3-x)\\x-18+6x=-15+5x\\x+6x-5x=-15+18\\2x=3\\x= \frac{3}{2}$

__________________________________________________________
b)
$10+8.(x+4)=-2x\\10+8x+32=-2x\\10x=-42\\x= \frac{-42}{10} \\\\x= \frac{-21}{5}$









Forte abraço!

Answer 2

a) x - 3.(6 - 2x) = - 5.(3 - x)
    x -18 +6x = - 15 + 5x
    x + 6x - 5x -18 +15 = 0
    2x - 3 = 0
    2x = 3
     x = 3/2 = 1,5

B) 10 + 8.(x + 4) = -2x
     10 + 8x + 32 = -2x
     8x + 2x +10 + 32=0
     10x + 42= 0
     10x = - 42
         x = -42/10 = -21/5 = - 4,2
