What the Expert Says:

Do you remember your teacher's favorite mnemonic for opperations? It's PEMDAS. I've copied the order of operations for you below.

The order to perform combined operations is called the PEMDAS rule.

If the expression consists of parenthesis, exponents, +, –, × and ÷, then the operations MUST be performed in the following order.

Always work on the calculations within parenthesis first if any.
Next, calculate the exponents.
Then, carry out multiplication or division, working from left to right.
Lastly, do addition or subtraction, working from left to right.

Note: A common mnemonic for PEMDAS is Please Excuse My Dear Aunt Sally.

First you must distribute the 2 by multiplying it to the terms in the parentheses.that will give you 6x-8-7=3x+1+x
Then you must combine like terms on both sides of the = which gives you 6x-15=4x+1
Then you must get the x's on one side by subtracting both sides by 4x. And yoy should get the 15 on the other side by adding 15 to both sides. This gives you 2x=16. Then divide both sides by 2 to get x by itself and the answer will be x=8

Distribute the left hand side and simplify the right hand side.
6x-8-7 = 4x+1
6x-15 = 4x + 1
6x-4x = 1+15
2x = 16
x = 8
