SOLUTION: Solve: |7x - 11| = 3 This is how I worked it out. |7x - 11| = 3 |7 x 2 - 11| = 3 |14 - 11| = 3 |3| = 3 Is that right? Thank you very much

Question 694561: Solve: |7x - 11| = 3
This is how I worked it out.
|7x - 11| = 3
|7 x 2 - 11| = 3
|14 - 11| = 3
|3| = 3
Is that right?
Thank you very much

You can put this solution on YOUR website!
When you do absolute values in equations to get rid of the absolute value you need to make two seperate equations one that represents the positive and negative
1.(7x-11)=3
2. -(7x-11)=3
Solve both
1.7x-11=3
7x=14
x=2
2.-(7x-11)=3
-7x+11=3
-7x=-8
x=8/7
{8/7, 2} your left with two answers in the solution set.
