Question

Is the point (-4,5) a solution to the following system?
2x-15y=33
-3x+4y=-5

Answer 1

To find out if it is or not, Sub the point \(P(-4,5)\) in for the first equation. If they both return true, then the point is a solution.

Answer 2

2(-4)-15(5)=33

Answer 3

So lets say:
\(2x-15y=33\)
\(2(-4)-15(5)=33\)
\(-8-75=33\)
\(-83\neq33\)

Answer 4

I don't think it is true?

Answer 5

You would be correct :-)
