Question

12x-32=53+7×
9×-18=36

Answer 1

$12x - 32 = 53+7$
$12x-7x=53+32$
$5x=85$
$x = \frac{85}{5}$
$\boxed{x = 17}$

$9x-18=36$
$9x=36+18$
$9x=54$
$9x=\frac{54}{9}$
$\boxed{x=6}$

Answer 2

Oii, bom vamos lá

12x - 32 = 53 + 7x
incógnitas de um lado
12x - 7x = 53 + 32
5x = 85
x = 17
-------------------
9x - 18 = 36
9x = 36 + 18
9x = 54
x = 6
