Question 6610: Hi,
I was review my textbook and I can not find an example of this problem.
The question is:
Use elimination to solve: x/3 + 4y = 30 and 2x - y = 5.
I appreciate the help.

You can put this solution on YOUR website!
x/3 + 4y = 30 and 2x - y = 5


x/3 + 4y = 30
multiplying by 3 we get,
x + 12 y = 90


so we have,
x + 12 y = 90
2x - y = 5
