SOLUTION: Please help me solve this problem. 6/(15x) +7/75-2/(3x) I think you should find the lcd which would be 75 I think but then I get confused with the x's. Thanks

This has to equal something to solve. As it sits, it's not
even a problem. I'll pick a number for it to equal, say
6%2F%2815x%29+%2B7%2F75-2%2F%283x%29+=+1%2F25
The LCD is 75x
Multiply both sides by 75x
30+%2B+7x+-+50+=+3x
7x+-+20+=+3x
4x+=+20
x+=+5
check answer:
6%2F%2815%2A5%29+%2B7%2F75-2%2F%283%2A5%29+=+1%2F25
6%2F75+%2B+7%2F75+-+10%2F75+=+3%2F75
13%2F75+-+10%2F75+=+3%2F75
3%2F75+=+3%2F75
OK
