is (7, 1) a solution to this system of equations?\n9x + 12y = 12\nx + 7y = 14\nyes\nno

Explanation:

Step1: Substitute x = 7 and y = 1 into first - equation

Substitute into $9x + 12y$: $9\times7+12\times1=63 + 12=75\neq12$ Since the left - hand side of the first equation does not equal the right - hand side when $x = 7$ and $y = 1$, we don't need to check the second equation.

Answer:

no
