Hi, would someone mind just checking the answer I got for this formula and tell me if I'm on the right track or not.
Answer I got...
x=84 y= -63
I didn't get that. Check your math. I found 7y=63 but not y = 63.
You can always check your answer. Is 4X = 3Y.
3*84 = 4*63 yes, it is.Is X + Y = 21. No, it isn't. I always check my answers before I call it quits on a problem.
yyes you are right
wat is the answer to this ?
solve by elimination
