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

Question

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

Answer 1

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