help

Answer 1

It's very important that you include the instructions that came with this problem. What are you looking to do with -15x+20xy-30y=10 ?

Answer 2

Solve for x and y

Answer 3

So, what would be your first move? You may choose whether to solve for x first or for y first.

Answer 4

Admittedly, this equation is harder to solve for x or y than would be a quadratic equation.

Why not try dividing the whole equation by 5, which happens to be the greatest common factor?

Why not look for the greatest common factor of the first two terms?

Answer 5

Hold it. Are you sure that the original problem was not \[-15x^2+20xy+30y^2=10?\]

Answer 6

Yes! I knew I was forgetting something thanks for the correction

Answer 7

So, have you any thoughts regarding what to do next? I spent a lot of time trying to find a way to factor the equation you originally posted.

Answer 8

Suggestion: Subtract 10 from both sides of the equation, so that all terms are on the left side, and then try to factor by grouping.
