Could you show me how this is done step by step?

Yes, pick a variable you'd like to eliminate (x or y).

x

If anything I say doesn't make sense, stop me and let me know.

ok

So what do you get when you multiply the first equation by \(\frac{-7}{5}\).

do you make the 55 a fraction then cross multiply

No, multiply both sides of the whole equation by -7/5

\[\frac{-7}{5}(5x+3) = \frac{-7}{5}(-7)\]
And simplify.

What do you get?

While you're working it out I'm gonna grab some coffee.

35+3 =-49

Right?

yes

ok

What do you get for the new equation that only has y's?

13/7(7x+2y)=13/7(13)

is this step right

oh ok

Now multiply that whole equation by 5 to get rid of the fraction

What do you get?

The equation on the bottom that only has y's that is.

so if i multiply all by 5 I get 10y -10=65+245

Then you combine your terms.

-31y=114

Right, and now y =?

Just leave it as a fraction.

-31/114

Yep. Now plug that in for y into either one of your original equations and solve for x.

Err wait, no. It's -114/31

thank you

Of course! =)

tag! your it
