Please do your own homework.

Welcome to Wikipedia. Your question appears to be a homework question. I apologize if this is a misinterpretation, but it is our aim here not to do people's homework for them, but to merely aid them in doing it themselves. Letting someone else do your homework does not help you learn nearly as much as doing it yourself. Please attempt to solve the problem or answer the question yourself first. If you need help with a specific part of your homework, feel free to tell us where you are stuck and ask for help. If you need help grasping the concept of a problem, by all means let us know.--Jasper Deng (talk) 21:08, 10 January 2017 (UTC)[reply]

Here are the steps you need to take:

1) Multiply out everything in parentheses.

2) Add like terms (integers add to integers, and X's add to X's) on each side of the equals sign.

3) Get all the X's on one side of the equals sign and all the integers in the other side thru addition or subtraction, and again add like terms.

4) Divide both sides by the coefficient in front of the X.

5) This will give you your answer for X. Plug it into both values of X in the original equation and solve both sides, and they should be equal, unless you made a mistake. This is your check. StuRat (talk) 22:53, 10 January 2017 (UTC)[reply]

For solve in the last sentence, read evaluate or compute. I, at least, don't go around solving one side of an equation. —Tamfang (talk) 02:25, 11 January 2017 (UTC)[reply]
