Question

Find the solution of this system of equations
-3x-7y=-66
-10x-7y=-24

Answer 1

First you probably just want to multiply either the top or bottom by -1

Answer 2

ILY?

Answer 3

Then you can use elimination

Answer 4

ok

Answer 5

Lol @iGreen who are you talking to and do you still need my help @usitdown or can you take it from here?

Answer 6

Still need help @ihateschool18

Answer 7

@ihateschool18 I'm talking to @usitdown he posted 'ILY @iGreen' to me..

Answer 8

Then he deleted it..

Answer 9

Okay so I just multiplied the first equation by negative one so now we have \[\frac{ 3x+7y=66 }{ -10x-7y=-24 }\] so after elimination we are left with -7x=42. So x=-6.

Answer 10

Nice work @ihateschool18

Answer 11

Now we plug x back into one of the original equation to get y.

Answer 12

Thanks

Answer 13

Is there a y value???

Answer 14

Yes, you plug it back into the equation.

Answer 18

\(-3x-7y=-66\)
\(-3(-6)-7y=-66\)
\(18-7y=-66\)
\(-7y=-84\)
\(y = 12\)

Answer 19

So your answer is (-6, 12) :)
