could someone help me solve this problem?

Question

Solve the formula for y

 

x/6 - y/7 =1

 

i get so confused with fractions!

Answer 1

The best thing to do is to multiply both sides by a number that is divisible by both 6 and 7. That number would be 6*7=42

 

 

so:             42* [x/6 - y/7]  =  42* 1

 

 

Therefore:    7x - 6y = 42             (this is probably the most important step)

 

 

Now you can just rewrite this as:             6y = 7x - 42

 

finally divide both sides by 6:              y = (7/6) x - 7

 

Let me know if you have any questions.
