Question

qual a resposta de:
$x + 3x = 120$
$3x - 4 + x = 12$
$2x + 4 = 6$
$3x + 2 = 10 - x$
$3(2x - 5) = 9 - 2x$
$5(2x + 3) = 24 + x$
$2(x + 5) = - 4$
$5(y - 3) = 2y + 3$
$- 8(x - 1) = - 16$
​

Answer 1

Resposta:

x = 120/3

x = 16/3

x = 2/2

x = 8/3

x = 24/8

x = 9/10

x = 10/64

y = 18/3

x = -24/8
