Example Question #1 : Map 8th Grade Math
Solve for
In order to solve for 
For this problem, the first thing we want to do is distribute the 
Next, we can subtract 
Finally, we divide 
Example Question #2 : Map 8th Grade Math
Solve:
In order to solve this problem, we need to recall our exponent rules:
When our base numbers are equal to each other, like in this problem, we can add our exponents together using the following formula:
Let's apply this rule to our problem
Solve for the exponents
We cannot leave this problem in this format because we cannot have a negative exponent. Instead, we can move the base and the exponent to the denominator of a fraction:
Solve the problem
Example Question #3 : Map 8th Grade Math
Use algebra to solve the following system of linear equations:
There are a couple of ways to solve a system of linear equations: graphically and algebraically. In this lesson, we will review the two ways to solve a system of linear equations algebraically: substitution and elimination.
Substitution can be used by solving one of the equations for either 
Elimination is best used when one of the variables has the same coefficient in both equations, because you can then use addition or subtraction to cancel one of the variables out, and solve for the other variable.
For this problem, substitution makes the most sense because the first equation is already solved for a variable. We can substitute the expression that is equal to 
Next, we need to distribute and combine like terms:
We are solving for the value of 
Then divide both sides by 
Remember, when we are solving a system of linear equations, we are looking for the point of intersection; thus, our answer should have both 
Now that we have the value of 
Our point of intersection, and the solution to the two system of linear equations is
