Answer :

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..

2x-5=3x-10

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=10-5

y=5

(5,5) is your solution.
