Question

Solve using elimination.
5x - y = 0
3x + y = 24

Answer 1

Some process. When you see -y and y, by adding you can tell they will cancel out. Add the two equations.

Answer 2

8y = 24
y=3

Answer 3

oops. i meant x.

Answer 4

Yeah, so now plug that x in for an equation.

Answer 5

Okay.

Answer 6

Did you get the answer?

Answer 7

So you have x = 3

3(3) + y = 24
9 + y = 24
y = 15

So x = 3 and y = 15
