Question

1) (500b-497b)/85=99
2)2244/(111z-9z)=22

Answer 1

1) (500b-497b)/85=99
500b-497b=99*85
3b=8415
b=8415/3
b=2805

2)2244/(111z-9z)=22
102z-9z=2244/22
102z=102
z=102/102
z=1

Answer 2

1) 3B = 99 * 85
3B = 8415
B = 2805
..............................................
2) 102Z = 2244 : 22
102Z = 102
Z = 1
