Question

84:(x-3)=12 va rog sa scieti toata rezolvare... ms mult

Answer 1

$\frac{84}{x-3} =12$

$12(x-3)=84$

$12x-12*3=84$

$12x-36=84$

$12x=84+36$

$12x=120$

$x= \frac{120}{12}$

$x=10$

Verificare: 84:(10-3)=84:7=12

Answer 2

12(x-3)=84
12x-12*3=84
12x-36=84
12x=48+36
12x=120
x=120:12
x=10
