WebFeb 13, 2024 · SOLVE A SYSTEM OF LINEAR EQUATIONS WITH THREE VARIABLES. Write the equations in standard form If any coefficients are fractions, clear them. Eliminate the same variable from two equations. Decide which variable you will eliminate. Work with a pair of equations to eliminate the chosen variable. WebFeb 10, 2024 · While quadratic equations have two solutions, cubics have three. You already have two of these — they're the answers you found for the "quadratic" portion of the problem in parentheses. In cases where your equation is eligible for this "factoring" method of solving, your third answer will always be . Factoring your equation into the form
