Answer:
x = 6
y = 2
Explanation:
From the second equation (x - 3y = 0) we know that x = 3y, now we just substitute 3y instead of "x" in the first equation and get...
x + 2y = 10
3y + 2y = 10
5y = 10
y = 2
Now we can find "x" since we know what "y" is equal to.
x + 2y = 10
x = 10 - 2y
x = 10 - (2)(2)
x = 10 - 4
x = 6
