Linear equations anyone? 5x + y = 61 y= 3x - 35 Halp?

OpenStudy (anonymous):

I'm so confused. xD

OpenStudy (anonymous):

So you're trying to solve a system of linear equations? (Let's check: 2 equations and 2 unknowns - yep this is doable).

OpenStudy (anonymous):

Yessir. I tried to solve it myself but it became really bizarre really quickly.

OpenStudy (anonymous):

\[5x+(3x-35)=61\] <-- so we'll substitute the second equation's definition of y for the y variable in the first equation. Next collect like terms and solve (divide through to coefficient) for x.

OpenStudy (anonymous):

OK what do you get?

OpenStudy (anonymous):

So x equals 12? So, then we plug it in to find y?

OpenStudy (anonymous):

And y equals one! Oh my goodness, thank you so much!

OpenStudy (anonymous):

Absoluumlutely!

OpenStudy (anonymous):

Thank you so much! Oh, bless!
