Repost Solving Linear Systems in Three Variables by Eliminating Variables1. Reduce the system to two equations in two variables. This is usuallyaccomplished by taking two different pairs of equations and using theaddition method to eliminate the same variable from both pairs.2. Solve the resulting system of two equations in two variables using additionor substitution. The result is an equation in one variable that gives the valueof that variable.3. Back-substitute the value of the variable found in step 2 into either of theequations in two variables to find the value of the second variable.4. Use the values of the two variables from steps 2 and3 to find the value ofthe third variable by back-substituting into one of the original equations.5. Check the proposed solution in each of the original equations. 9:274(5
