Question

Solve by the elimination method.
2x + 3y = 18
5x – y = 11

Answer 1

Give me a second.

Answer 2

okey dokey :)

Answer 3

5(2x + 3y) = 18
and
2(5x - y) = 11

Do you understand why I did that?

Answer 4

So now you are left with
10x + 15y = 18
and
10x - 2y = 11

Answer 5

The two "x"s cancel out so you have 17y = 7

Answer 6

divide and what does x equal

Answer 7

but now you need to find Y

Answer 8

so substitute what you got for X in to find Y

Answer 9

oh ok i kind of understand 7/17?

Answer 10

for x?
