Example Question #248 : How To Solve One Step Equations

Solve the following equation for :

 

Possible Answers:

No solution

Correct answer:

Explanation:

In order to solve for , we need to get the variable by itself on one side of the equation. For our problem,  is being added to , so the variable is not by itself. However, we are able to subtract  from both sides of the equation and still keep it balanced. Hence, our answer is .

Example Question #249 : Algebra 1

Solve for : .

 

Possible Answers:

Correct answer:

Explanation:

In order to solve for in the above equation, we must isolate it on one side of the equation. We can do this by applying an operation to that is the inverse (opposite) of what's currently being applied to .

Given , we see that  is being subtracted from , so we need to add  to both sides of the equation to isolate :
