is (-1, -2) a solution to this system of equations? 12x - 2y = 13 14x - 4y = -6 yes no

Explanation:

Step1: Substitute into first - equation

Substitute (x=-1) and (y = - 2) into (12x-2y). [12\times(-1)-2\times(-2)=-12 + 4=-8\neq13] Since the left - hand side does not equal the right - hand side of the first equation when (x=-1) and (y = - 2), we don't need to check the second equation.

Answer:

no
