Question

6x-3y=20 through (4,-3)

Answer 1

Well x = 4 and y = -3 so what we would do is plug in the numbers like this.
6 x 4-3 x -3 = 20 
Then lets break down the problem.
6x4=24 and 3x-3=-9
Now plug those numbers into our equation.
24 - (-9)=20
Then figure out the problem.
24 - (-9) = 33 
So the x,y is wrong.
