Mathematics Knowledge

Today I present an example of algebra with fractions.

If ¾x + 3 = 18, what does x equal?  Do you know how to solve this problem?

As an ASVAB tutor, I focus heavily on teaching the students in my ASVAB prep course about algebra.  One of the algebra topics is algebra with fractions.  I realize that when it comes to math, some people become overwhelmed by fractions, while others are overwhelmed by algebra.  This problem combined both topics into one.  Do you know how to solve this problem?  I will present the answer and explanation tomorrow.
