Question

How do i find all solutions of system of equations for 1.) x+squareroot(y)=0 2.)y^2-2x^2=15? And also for...?

Find all solutions of system of equations for this one solution.

{5/x-3/y=1

{-10/x+7/y=1

Please show how to solve these two problems thankyou so much for your time.

Answers

To solve a system of equations, first isolate one of the variables in the first equation so you get something like x = , and then substitute the thing on the right everywhere you see an x in the second equation. You can then solve for y. After you have a number for y, plug that back in to the expression for the first equation to get the numerical value for x.
