Question

Aflati-l pe,, a" din egalitățile
A: 3+2=80: 4
94: a-5=6×7
A: (120-2×55) -5=360: 10: 4
91: (a+6) +120: 10=75: 3
30: (a+3) +70: 2=82: 2
(36+a): 2+78: 2=2×32

Answer 1

A:3+2=20
A:3=20-2
A=18x3
A=54

94:a-5=42
94:a=42+5
A=94/47

A:(120-110)-5=36:4
A:10=9+5
A=14x10
A=140

91:(a+6)+12=25
91:(a+6)=25-12
A+6=91:13
A=7-6
A=1


30:(a+3)+35=41
30:(a+3)=41-35
A+3=30:6
A=5-3
A=2

(36+a):2+39=64
(36+a):2=64-39
36+a=25x2
A=50-36
A=14
