solve the system using substitution
{x+2y=11
{3x+2y=13
i just told you how to do the other one; it's the same exact method. solve for x and y. you get: x=2y+11 and y=(1/2x)+(11/2). then plug them both back into the original equation (either one, it doesn't matter); you get, x=11, and y=0. the points would be (11,0)
thats not one of the options on the multiple choice though....
they are....
a(1,5)
b(16,2.6)
c(1,6)
d(12,0.5)
I'm so sorry, I put 11 where I should have put 13. The answer is A) 1,5. That's right. Sorry again.
