use subtraction method....
Y 3X = 10
(Y 2x = 5) Y + 2X = 5
so...
Y 3X = 10
Y + 2X = 5
X = 5
X = 5 Now fill in the 5 for X and Y = 5

If you're looking for a solution for both equations and had a choice between the 3 ways of solving it, I would choose substitution for this problem. So..2x5=3x10
Move like terms to their own sides.
Take 2x away from both sides, and add 10 to both sides. That should leave you with
5=x
Now that you have the x, plug it into the equation that works best for you to solve.
That should be y=2(5)5
y=105
y=5
(5,5) is your solution.
