5x + 3 = 7x - 1. Find x

a. 1/3

b. ½

c. 1

d. 2

Step-by-step explanation:

First you need to get like items on the same side (put the variables on one side and the non-variables on the other). Remember anything you do on one side of the equal, you have to do on the other side, too.

5X+3=7X-1 I'm going to move the - 1 first, but you don't have to as long as you keep the equation equal.

5X+3+1=7X-1+1 We know that + 1-1 is zero and so is - 1+1. So

5X+3+1=7X We don't need to keep that zero.

5X+4=7X Now, we want to move the 5X over.

5X-5X+4=7X-5X Simplify and get rid of the zero.

4=2X Last, we have to divide to get the 2 away from the X.

4/2=2X/2 Not everyone know that slash mean divide, : -).

2=X
