Question

50x + 200 = 20 (x - 4 ) + 100

Answer 1

50x +200 = 20x - 80 +100
50x - 20x = 20 - 200
30x = 180
x = 180/30
x = 6

Answer 2

Explicação passo-a-passo:

$50x + 200 = 20(x - 4) + 100$

$50x + 200 = 20x - 8 0 + 100$

$50x + 200 = 20x + 20$

$50x - 20x = 20 - 200$

$30x = - 180$

$x = - \dfrac{180}{30}$

$x = > - 6$
