Example Question #181 : Grade 8

Solve for 

 

Possible Answers:

Correct answer:

Explanation:

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:

Solve for 

 

Possible Answers:

Correct answer:

Explanation:

In order to solve for , we need to isolate the  to one side of the equation. 

For this problem, we want to combine like terms. Let's start by moving the  values to one side:

Next, we can subtract  from both sides:

Finally, we divide  from 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.

1

Possible Answers:

Correct answer:

Explanation:

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:
