Question

(24+ x ) : 3 =10
(X+72):4 = 20
(56+x):2=30
( 17+ x) :3= 10
dau coroana la primul plss si 11 puncte

Answer 1

24+x=30->x=6
x+72=80->x=8
17+x=30->x=13

Answer 2

(24+ x ) : 3 =1024+x=10·3
24+x=30
x=30-24
x=6

(X+72):4 = 20
x+72=20·4
x+72=80
x=80-72
x=8

(56+x):2=30
56+x=30·2
56+x=60
x=60-56
x=4

( 17+ x) :3= 10
17+x=10·3
17+x=30
x=30-17
x=13
