Solve the absolute value equation.
I I will represent absolute value
I 2x4 I 1= 11
Would the solutions be x=8 and x= 4?

I just mentally tested x=8.
It did not work in your equation
take the 1 to the other side and follow the steps I just showed you in the previous problem
I did take the 1 to the other side. Here's exactly how I did it:
I 2x4 I 1=11
added 1 to both sides
That came out to:
I 2x4 I =12
I separated it into
2x4=12 and 2x4=12
add 4 to both sides of each
2x=16 and 2x=8
divide each by two
x=8 and x= 4
What part of my figuring is off?

I am sorry, you are right!!!!!
Three strikes, I guess I am out
