Question

Solve: 9c /7-6c=15
Solve :3f+4/2-6f =-2/5

Answer 1

1.9c/7-6c=15

Lcm = 7

So. 9c-42c/7=15

By cross multiply we get,

9c-42c=105

33c=105

C=105/33

By cancellation we get c=35/11

2. 3f+4/2-6f=2/5

Lcm=2

So. 6f+4-12f/2=-2/5

-6f+4/2=-2/5

By cross multiply we get,

-30f+20=-4

-30f=-24

f=-24/-30

f=4/5
