Question

Determine if ( 5 2 , 7 2 ) and (-4,10) are solutions to the system of equations: x + y = -6 6x2 + 9y = 6

Answer 1

We don't know what ( 5 2 , 7 2 ) is supposed to represent, but it seems unlikely that the sum of those numbers is -6. Hence that is not a solution to the system.

The sum of -4 and 10 is +6, not -6, so that point is not a solution, either.

Neither offering is a solution to the equations.
