If you are told that two-thirds a number plus 4 is 7 and you wish to figure the number you can make an algebra formula: (2/3)X + 4 = 7
To simplify the formula you want to get the X alone. Begin by subtracting 4 from each side. (2/3)X + 4 - 4 = 7 - 4, so you now have (2/3)X = 3. To get the (2/3)X to be just 1X multiply each side by 3/2, so ((2/3)X)x(3/2) = 3x(3/2) giving you X=4.5</span>
