Re: systems of equations

hi mathhelppls2020

Welcome to the forum.

These are fractions?

If you multiply by the common denominator, 10xy, you get an equation without the complication of fractions:

Now make y the subject:

Repeat with the other equation and set the two expressions (in x) equal.  That way you can solve for x.
