X=5-3Y

X=2Y-10

Whats the answer

X = 5 - 3y

x = 2y - 10

5 - 3y = 2y - 10

+ 3y + 3y

5 = 5y - 10

+ 10 + 10

15 = 5y

5 5

3 = y

x = 2y - 10

x = 2 (3) - 10

x = 6 - 10

x = - 4

(x, y) = (-4, 3)

Y=3

x=-4

you have to use substitution. so instead of the equations having two variables, they will now have one.

5-3y=2y-10 after solving for y, plug the answer in any of the equations and you will find x.
