Since we want to solve for x, we need to get x by itself. Since 147 is being added to x, subtract 147 from both sides. This will cancel out the 147 and leave x by itself.
Area = Length times width. Since division and multiplcation are inverse operations, we can do 24 divided by 3 to get 8, so to get the area of 24, you would do 8 x 3.
