Question 201925: Please! help me with this. thank you so much!!!
6x+5y=-3
-5x+y=49
y=49+5x
6x+5(49+5x)=-3
6x+245+25x=-3
31x+248
x=-8
y=??? and how??

You can put this solution on YOUR website!
You're doing great, you just need to find "y".


y=49%2B5x Start with the isolated equation (that you found earlier)


y=49%2B5%28-8%29 Plug in x=-8


y=49-40 Multiply


y=9 Combine like terms.



So the solutions are x=-8 and y=9.


Which form the ordered pair .


This means that the system is consistent and independent.
