One-step and two-step equations & inequalities.
The perimeter of a rectangle is equal to 2 times the length plus 2 times the width. We can solve for the length by isolating it on one side of the equation. We do this by subtracting 2 times the width from both sides, and then dividing both sides by 2. This gives us the formula for the length.
Let's practice some two step equations, some of which require merging terms and using the distributive property.
A two-step equation is an algebraic equation that takes you two steps to solve. You've solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.

for example 4/5 / 5/6 can be written as 4/5 divided by 5/6 so the answer is 24/25 and simplify fractions is the same as solving it. Use this http://www.wikihow.com/Simplify-Complex-Fractions
