In this video we learn how to solve systems of equations with elimination / combination.

In this video, we use our background of solving linear systems to solve a nonlinear system.

In this video we solve two systems of nonlinear equations. The first has an absolute value function and a circle (and we solve by graphing). The second has a linear function and a quadratic.

A literal equation is an equation with more than one variable. These problems will sometimes have you solve for a variable, so that your solution is in terms of other variables. This will happen very often in formulas for science.

In my second video over literal equations, we do problems that are slightly more challenging. We solve one problem for the variable that is in the denominator and solve two word problems.

This is the second of two videos on solving systems of equations using the substitution method.

This is the first of two videos on solving systems of equations using the substitution method. Make sure to watch "Solving Systems by Substitution 2" for help with solving systems when both equations are in standard form!

This is the first of two videos on solving systems by elimination or combination. Be sure to look for my second video on this topic (coming soon).

In this video you will learn how to solve equations with variables on both sides, such as 3x + 3 = x + 7

In this video, you will learn how to solve equations that have fractions by eliminating the fractions first. You will accomplish this by multiplying each side of the equation by the denominator of the fraction you are trying to eliminate

This video practices solving systems of equations by substitution and elimination.
