A . 3636 : ( 12 x X - 91 ) = 36
( 12 x X - 91 ) = 3636 : 36
( 12 x X - 91 ) = 101
12 x X = 101 + 91
12 x X = 192
X = 192 : 12
X = 16
B . (X: 22+ 45) x67= 8911
(X: 22+ 45) = 8911 : 67
(X: 22+ 45) = 133
X: 22 = 133 - 45
X: 22 = 88
X = 88 x 22
X = 1936
C . (X +74) -318= 200
X + 74 = 200 + 318
X + 74 = 518
X = 518 - 74
X = 444
D . 5x X- 18 = 8+9
5x X - 18 = 17
5x X = 17 + 18
5x X = 35
X = 35 : 5
X = 7
L . 1440: (125- X) =12
125 - X = 1440 : 12
125 - X = 120
X = 125 - 120
X = 5
