13x + 10y = 203
26x + 18y = 394
multiply the 1st equation by 2 and subtract the 2nd, and you have
2y = 12
and the x has been eliminated.
I can figure out how to use elimination here. I tried but I didn't do it right.
13x + 10y = 203 26x + 18y = 394
How do you use elimination to find the point of intersection?

Wait so you're suposed to subtract the problem?
I was taught to add them.... THAT'S WHY I NEVER GOT IT RIGHT!
well, I guess you could multiply by -2 and then add. Same "difference" in the "sun" total, yeah?
