Question 18120: Prove that (4,3)is or is not a solution to the system.
x+2y=10
3x+5y=3 Found 2 solutions by Earlsdon, tutor4u:Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! To prove this, you need only to substitute the x and y-values of the given point into both equations and see if they satisfy them both.
If both equations are satisfied by the coordinates of the given point ( 4, 3), then the given point is a solution to the system; if they aren't, then it isn't.
= 10 This one is ok.
= 27 This is not = 3, so the given point (4, 3) does not satisfy the system of equations.
