x-2y=-1
Answer by askmemath(368)   (Show Source):
You can put this solution on YOUR website! Simply substitute the points in place of X and Y in the equations. If the points satisfy the equation, then it is said to be a solution
For e.g. (1,1) and 2x+y = 3
Substituting
Left Hand side
2(1)+ 1
= 2+1
= 3
= Right Hand side
Thus (1,1) is a solution of the equation 2x+y = 3
Can you solve for the rest?
