To determine if (2,1) is a solution to the system of equations, we need to substitute x = 2 and y = 1 into both equations and see if they satisfy both equations.
For the first equation:
8(2) + 7(1) = 16 + 7 = 23, which is not equal to 11.
For the second equation:
2 + 1 = 3, which is equal to 3.
Since (2,1) does not satisfy the first equation but satisfies the second equation, it is not a solution to the system of equations.
Is (2,1) a solution to this system of equations?
8x+7y=11
x+y=3
