Answer 1

(48-x):2-9:3+5=10
(48-x):2-3=10-5
(48-x):2-3=5
(48-x):2=5+3
48-x:2=8
48-x=8×2
48-x=16
x=48-16
x=32

verificare :

(48-32)÷2-9:3+5=
16:2-3+5=8-3+5=5+5=10

Answer 2

( 48 - x ) : 2 - 9 : 3 + 5 = 10

( 48 - x ) : 2 - 3 + 5 = 10

( 48 - x ) : 2 - 3 = 10 - 5

( 48 - x ) : 2 - 3 = 5

( 48 - x ) : 2 = 5 + 3

( 48 - x ) : 2 = 8

48 - x = 8 × 2

48 - x = 16

x = 48 - 16

x = 32 => numărul aflat
