Solve equations algebraically

Use elimination to solve for the common solution in the two equations: x + 3y = 4 and 2x + 5y = 5. x= –5, y= 3. Multiply each term in the first. This approach to solving equations is based on the fact that if the product of two quantities is zero, then at least one of the quantities must be zero.When given two equations in two variables, there are essentially two algebraic methods for solving them. One is substitution, and the other is elimination.Algebra Calculator shows you the step-by-step solutions! Solves algebra problems and walks you through them.There are two methods that will be used in this lesson to solve a system of linear equations algebraically. They are 1) substitution, and 2) elimination.
