Frequently Asked Questions

How can I solve algebra problems?

Solve an equation for one variable. If you have only one unknown in your word problem, isolate the variable in your equation and find which number it is equal to. Use the normal rules of algebra to isolate the variable. Remember that you need to keep the equation balanced.

What is the solution to the system equation?

In this case the two equations describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) will satisfy the equation of either line. Thus the pair (x, y) is the one and only solution to the system of equations.

What are the three methods for solving system of equations?

The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.

How do you solve system of three equations?

One way to solve this system of equations is to multiply the second equation on both sides by 3 (which doesn't alter the equality of the two sides) and then add the resulting equation from the first equation.
