How to solve for 4(2x-1)-7=4-x+6 step by step

The answer is x = 7/3

Step-by-step explanation: You start by solving the variable in brackets on the left side of the equation

4(2x - 1) - 7 = 4 - x + 6

(8x - 4) - 7 = 4 - x + 6

8x - 4 - 7 = 4 - x + 6

At this point, you collect like terms by bringing the unknown variables to the left side of the equation and the known variables to the right side of the equation

However, you must remember that each sign changes to the opposite as it crosses from one side of the equation to the other side (for example, + becomes - and, - becomes +). Therefore the equation can be re-written as;

8x + x = 4 + 6 + 4 + 7

9x = 21

Divide both sides of the equation by 9

x = 21/9

x = 7/3 (or 2 1/3)

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
