For this case we have the following system of equations:

[tex]2x + 4y = 36\\3x-4y = -6[/tex]

We must verify if the point[tex](x, y) :( 4,7)[/tex] is a system solution.

Substituting we have:

First equation:

[tex]2 (4) +4 (7) = 36\\8 + 28 = 36\\36 = 36[/tex]

Second equation:

[tex]3 (4) -4 (7) = - 6\\12-28 = -6\\-16 = -6[/tex]

Equality is not fulfilled, so the point is not a system solution.

Answer:

The given point is not a system solution
