What is the last step to solving a system of equations?
The last step to solving a system of equations is to check the solution by substituting the values back into the original equations and verifying that they are true for both equations.
The last step in solving a system of equations is checking the solution by substituting the values of the variables back into the original equations to ensure they satisfy all the equations. This step is important to verify that the values obtained are indeed the solutions to the system of equations.
The last step to solving a system of equations is to check your solutions by substituting them back into the original equations. This step is important to ensure that the values you obtained for the variables satisfy all the equations in the system.
To check the solutions, substitute the values of the variables you found into each equation one by one. If the equation holds true after substituting the values, then the solutions are correct. If any of the equations do not hold true, you need to revisit your steps and check for any errors made during the solution process.
It is important to perform this check to avoid any errors or mistakes in solving the system. In some cases, there might be multiple solutions or no solutions at all, and the check process helps to confirm the validity of the obtained solutions.
