Answer:
If you are doing x - 8 = 3, then x = 11
Explanation:
Remember PEMDAS and whatever you do to one side of the equation, you have to do to the other side.
x - 8 = 3
First, add 8 to the -8 to cancel it out and isolate the variable. Since you are adding 8 to the left side of the equation, you have to add 8 to the right side as well
x - 8 + 8 = 3 + 8
Simplify.
x = 11
You can check your answer by substituting the variable.
11 - 8 = 3
This equation is true. Therefore x = 11.
