Question

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

Answer 1

No.

Explanation:

5x + 3y = -4

For (4, 6) to be a solution, 4 must be put in for x and 6 for y and the solution must be -4.

(5 * 4) + (3 * 6) = 20 + 18 = 38

Since 38 is NOT equal to -4, (4, 6) is not a solution.

Hope this helps!

Answer 2

False

Explanation:

5x+3y =-4

Substitute the point into the equation and see if it is true

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

20 +18 = -4

38 = -4

This is false so the point is not a solution
