Answer:

x = 4

y = 1

Explanation:

This is a systems of equations problem, and while there are multiple ways to solve, my mind immediately goes to substitution.

x + 2y = 6 is easily converted into the value of x:

x = 6 - 2y

Using this, you can substitute that in for the x of the other equation and solve for y.

3 (6 - 2y) - 2y = 10

18 - 6y - 2y = 10

18 - 8y = 10

-8y = -8

y = 1

If you want the other variable (x), you can just plug in the value of y into any of the original equations.

x + 2(1) = 6

x = 4

I hope this helped!
