Question

Observă rezolvarea model, apoi află valoarea lui x din exercițiile date.
c. ( X : 3-3) × 9=306
d.( X : 2)×3=30×3
e.(7 × 9 - X ×5)-27:9=20​

Answer 1

c. ( X : 3-3) × 9=306
X:3-3=306:9
X:3-3=36
X:3=36+6
X:3=42
X=3x42
X=126
d.( X : 2)×3=30×3
( X : 2)×3=90
X:2=90:3
X:2=30
X=30x2
X=60
e.(7 × 9 - X ×5)-27:9=20
(63-X x5)-3=20
63-X x5=20+3
63-X x5=23
X x5=63-23
X x5=40
X=40:5
X=8
