To check if the point (5, 6) is a solution to the linear system of equations, you need to substitute the values of x and y into each equation and verify if both equations hold true.
Therefore, the correct choice is:
B. Substitute 6 in for x and 5 in for y in both of the equations to see if both equations are true.
However, note that the traditional way to represent the point (5, 6) would be to substitute 5 for x and 6 for y, as x corresponds to the first number and y to the second number in the ordered pair. So it is worth clarifying that you would be checking using:
- Substitute 5 for x and 6 for y in both equations.
But in the context of your options, B is the most comprehensive approach described.
