Question

Calculeaza 10×3-2×a=14
a:(63:7)+1=10
(a×5):2=40:4
( b:3)×6=52-4
9×(c:6)=6×6
60-(e×9)=30:5

Answer 1

30-2a=14 2a=16 a=8
a:9+1=10 a:9=9 a=81
5a:2=10 5a= 20a=4
(b:3)×6=48 b:3=8 b=24
9×(c:6)=36 c:6=4 c=24
60-(e×9)=6 e×9=60-6 e×9=54 e=6

Answer 2

10 x 3 - 2 x a = 14
30 - 2 x a = 14
2 x a = 30 - 14
2 x a = 16
a = 16 : 2
a = 8

a : (63 : 7) + 1 = 10
a : 9 + 1 = 10
a : 9 = 10 - 1
a : 9 = 9
a = 9 x 9
a= 81

(a x 5) : 2 = 40 : 4
(a x 5) : 2 = 10
(a x 5) = 10 x 2
a x 5 = 20
a = 20 : 5
a = 4

(b : 3) x 6 = 52 - 4
(b : 3) x 6 = 48
(b : 3) = 48 : 6
b : 3 = 8
b = 8 x 3
b = 24

9 x (c : 6) = 6 x 6
9 x (c : 6) = 36
( c : 6) = 36 : 9
c : 6 = 4
c = 4 x 6
c = 24

60 - (e x 9) = 30 : 5
60 - (e x 9) = 6
(e x 9) = 60 - 6
e x 9 = 54
e = 54 : 9
e = 6
