+216 Can someone help me with this problem I put in the answer 157 but it says its wrong.
+118677 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.
