Solve each system of equations using substitution.

Since these are all similar, I'll do one and you can come on back if you get stuck or just want confirmation of your answers.
from the first equation,
y = 2x+3
Now substitute that into the second equation:
5x - (2x+3) = -3
3x - 3 = -3
3x = 0
x = 0
so, y = 3
