Is (7,-2) a solution to this system of equations? 8x-20y=-4 18x+y=-12 yes no

To determine if is a solution to the system of equations, we need to substitute the values of and into both equations and check if they hold true.Let's start with the first equation: Substituting and : Since the left side does not equal the right side, is not a solution to the first equation. Therefore, we do not need to check the second equation.The answer is: no
