Question 483901: (5, 1) is a solution to the equation 2x - 3y = 7. What does this mean?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! (5,1) is the coordinate pair of (x,y)
x is equal to 5 and y is equal to 1.
the equation is 2x - 3y = 7
if you replace x with 5 and y with 1, then the equation should be true.
let's do that.
2x - 3y = 7 becomes:
(2*5) - (3*1) = 7 which becomes:
10 - 3 = 7 which becomes:
7 = 7
the equation is true when we replace x with 5 and y with 1.
that means that the coordinate pair of (5,1) is a solution to the equation of 2x - 3y = 7.
