Example Question #181 : Grade 8
Solve for
In order to solve for , we need to isolate the to one side of the equation.
For this problem, we need to multiply each side by
Next, we need to combine like terms, so we subtract from both sides:
Finally, we can divide by both sides:

Example Question #1 : Understand That The Solution Of A System Of Two Linear Equations Is The Intersection Of Their Lines: Ccss.Math.Content.8.Ee.C.8a
Identify the point of intersection by solving for the solution of the system of equations in the provided figure.
The graph displays a system of two linear equations. The point where these two lines intersect is the solution to the system of the equations because that coordinate point is the point that both lines have in common, or pass through.
In this case, the solution to the two linear equations that are displayed in the graph is the following point:
