We wrote the answer as an ordered pair. Solving three-variable, three-equation linear systems is not more difficult than solving the two-variable systems, it does take longer. What we do is change the 3x3 system to a 2x2 system by eliminating one of the variables using the elimination, then we solve the 2x2 system as we have done before. The students realized that using the equations when solving was the most effective method for systems of equations in situations. To solve systems using substitution, follow this procedure: Select one equation and solve it for one of its variables. In the other equation, substitute for the variable just solved. Solve the new equation. Substitute the value found into any equation involving both variables and solve for the other variable. Check the solution in both original equations. Verify whether or not the given ordered pair is a solution to the system. In our previous post, we have seen how to solve linear equations using elimination method by addition or subtraction where the coefficients of one of the variable is either same or additive inverses.

Suppose in the given system of equations, the coefficient of either variables are not additive inverse or not the same then we have to use Before we get into solving systems of linear equations via the elimination method, let's first consider and understand what it means to "solve" a system of equations. When we say "solve", with regards to linear, quadratic, exponential, or any other type of equation, what we really mean is that we are trying to find values of 'x' — the The substitution method requires that we solve for one of the variables and then substitute the result into the other equation. After performing the substitution step, the resulting equation has one variable and can be solved using the techniques learned Step 1:Rewrite the linear equations in slope-intercept form.
