Witch expression has a value of 6 when b equals 3?

Answer 1

Using the form mx+b:

mx+3=6

mx=3

m=3/x

(3/x)x=3

3x/x=3

3=3

x=Anything you want!

The value x gets removed on the division of 3x by x.

If you want an answer with less range, give me more information on either m or x.

Using the form x2+b:

x2+3=6

x2=3

x is approximately 1.732.
