Question

află nr. necunoscut 22- 5* (38-4*g ) egal 12

Answer 1

/=impartire
*=inmultire

22-5*(38-4*g)=12
5*(38-4*g)=22-12
5*(38-4*g)=10
(38-4*g)=10/5
38-4*g=2
4*g=38-2
4*g=36
g=36/4
g=9
4*9=36

Answer 2

22 - 5 *(38 - 4*g) = 12 
-5*(38 - 4*g) = 12 - 22
38 - 4*g = $\frac{-10}{-5}$
-4*g = 2 - 38
g = $\frac{-36}{-4}$
g = 9
