I have a few questions on systems of linear equations. I tried them and either i get a negative answer that should be positive, or vice versa. I checked the answers on the back of the textbook and answers were different than mine. Please help.
Solve by elimination.
What i did to solve:
-116 = 29y
I use the same process to find x. x=-9
my answer (x,y) = (-9,4)
textbook answer (x,y) = (9,-4)
what did i do differently? where did i go wrong? help
Solve by elimination:
how do i break this down to solve?
i tried and ended up with y=2, text said x,y = 3,4
