Is (1, 2) a solution to this system of equations?

Is (1, 2) a solution to this system of equations?
3x + 8y = 19
x + 4y = 9

Answer

To determine if (1, 2) is a solution, substitute x = 1 and y = 2 into both equations:

For the first equation: 3(1) + 8(2) = 3 + 16 = 19. This is true.
For the second equation: 1 + 4(2) = 1 + 8 = 9. This is true.

Since both equations are satisfied, the answer is yes.
