whats the answer
Step 1: add 3/8s to both sides (on the left side, this will cancel out the -3/8 and on the right side you add them together)
Step 2: Simplify 4/8 because it is not in its lowest terms (meaning both numbers can still be divided by the same number.
n=4/8 (both of these numbers have 4 as a common factor so they can both be divided by 4. Remember what you do to the denominator you must also do to the numerator).
(4/4=1 and 8/4=2)
