Question

Is (-5,6) a solution for 4x + 3y = 9

Answer 1

Nope

Explanation:

Insert (-5,6) to the problem:

4(-5) + 3(6) = 9

-20 + 18 = 9

-2 = 9

(-5,6) is not the solution.

Answer 2

No.

Explanation:

Insert the x and y, (-5 is x and 6 is y) into the equation. It should look like 4(-5)+3(6)=9. 4(-5)=-20 and 3(6)=18. -20+18=2 not 9.
