To solve for X, you first add the integers together and the X variables together. Then you subtract 3 from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 154
3X + 3 = 154
3X + 3 - 3 = 154 - 3
3X = 151
3X/3 = 151/3
X = 50 1/3
Since 50 1/3 is not an integer, there is no true answer to this problem.
