I'm seeking help on my equations too

@BrightEyes add your two equations. Your x term will get cancelled, leaving an equation just in y. solve for y, and plug back the value of y found into either of the equations. this will give you the value of x.

To verify if the answer you found is right, substitute the values of x and y found in the left hand side of both your equations and calculate. they should be equal to the numbers on the right hand side.
