What is the last step to solving a system of equations?

Question

Make a table of solutions of the linear equations
Graph the lines
Check the answer
Estimate the intersection point

Answer 1

The last step to solving a system of equations is to check the answer. This involves substituting the values of the variables found in the solution back into the original equations to verify that they satisfy both equations simultaneously. If the values work in both equations, then the solution is correct.
