• Check the answer.

Is (-2, 6) a solution to the system of these linear equations: x + 2y = 10 and 3x + y = 0? Why? (1 point)

• No, because the graphs intersect at (-2, 6).
• Yes, because the graphs don't intersect at (-2, 6)
O Yes, because the graphs intersect at (-2, 6).
O No, because the graphs don't intersect at (-2, 6).

• Yes, because the graphs intersect at (-2, 6).

The last step to solving a system of equations is to check the answer.

The last step to solving a system of equations depends on the method you used to solve it. There are three common methods: substitution, elimination, and graphing.

If you solved the system of equations by substitution, the last step would be to check the answer by substituting the found values into the original equations and ensuring that the solution satisfies both equations.

If you used the elimination method, the last step would be to solve for the remaining variable using the values you found for the other variables.

If you graphed the lines to solve the system, the last step would be to find the coordinates of the intersection point, which represents the solution to the system.

In summary, the last step can vary depending on the method used, but it usually involves checking the solution or finding the coordinates of the intersection point.
