Math Help Pls

Rather than just telling us what you 'put in' you could tell us how you found 157??

 

anyway, you have p+q=pq    and   p-q=7

so

p= 7+q

7+q+q = q(7+q)

 

Now solve it as a quadratic equation to find p and q and to do all the substitutions.

I have done it, but i have not checked imy answer, and the arithmetic in it is horrible.

But it is just a matter of slugging it out.

 

If you want more help it is up to you to demonstrate how far you can get on your own.
