|3x + 9|=20

the solutions arex=11/3, x=-29/3

Mr. Bacon
3x+9=20
3x=11
x=11/3

3x+9=-20
3x=-29
x=-29/3

Did the Absolute numbers confuse you?

Refresher:

|11| = 11

i got x=-2 +- square root of 10 Wait wait. Is that x over x to the power of negative 1? Or is it x over x minus 1?

Nice edit, twanger.

I was able to do that, and I'm in 8th grade... What's the point of the absolute value lines in it, though?
