What is the last step to solving a system of equations make a table of solutions estimate the intersection point check the answer or graph the lines

Answer 1

The last step to solving a system of equations depends on the method used to solve it.

If the equations were solved using the substitution method, the last step would be to substitute the found values of the variables back into one of the original equations to check if the solution is correct.

If the equations were solved using the elimination method, the last step would be to substitute the found values of the variables back into one of the original equations to check if the solution is correct.

If the equations were solved using matrices or determinants, the last step would be to verify the solution by substituting the values back into all of the original equations.

If the equations were solved using graphing, the last step would be to graph the lines and find the point of intersection visually.

So, based on the given options, the last step to solving a system of equations could be "check the answer" or "graph the lines," depending on the method used to solve the system.

Answer 2

is it check the answer or graph the lines?

Answer 3

It depends on the method used to solve the system of equations. If the method involved algebraic manipulation, such as substitution or elimination, then the last step would be to check the answer by substituting the found values back into the original equations. However, if the method used was graphing, then the last step would indeed be to graph the lines and visually determine the point of intersection.
