Child, that's a system of equations, listen here.
Equation 2 is almost perfect for the Substitution method.
Subtract 2y from both said of that and you get x = -2y +4
Take that and replace it with the x in equation one; 2(-2y +4) - 3y = 8
Distributive property and solve for y; -4y - 3y + 8 = 8
y = 0
Take that and go to Equation 2; x + 2(0) = 4
Distribute and solve for x; x + 0 = 4
x = 4
Now put both back in equation 1 to check them
2(4) - 3(0) = 8
8 = 8 Therefore, correct

I'll post Elimination in a minute
EliminaTION!
Equation 2, yet again, is almost perfect for elimination
Multiply Equation 2 by -2 giving you -2x + 4y = -8
You know have that and Equation 1, add the two equations together and you knock out x y = 4
Take that y put it in equation 1, solve for x, take x and y put it in equation 2 to check your work
