Tutoring to help you understand the concept not memorize facts

Order of operations is the concept to think about

In this case what is in parentheses (2-3x) can not be simplified.

You must work through the problem to removed the parenthesis and in this case the - (2-3x) must be multiplied through. Parenthesis is first then multiplication and division.

Answer: -2+3x

Leaving 4x-2+3x-5

Now you can combine the Xs by adding the 4x+3x to get 7x and the 2-5 to get -3

7x-3

In order to solve for X now that you have all the Xs combined and the intergers combined you would have to place the 3 on the other side of the =.

7x-3= 0

+3= +3

7x= 3

Now you have 7Xs so you have to divide the 7 on both sides

7x= 3

7 7

x= 3/7
