Step 1: Simplify both sides of the equation.
n+2=−4−n
n+2=−4+−n
n+2=−n−4
Step 2: Add n to both sides.
n+2+n=−n−4+n
2n+2=−4
Step 3: Subtract 2 from both sides.
2n+2−2=−4−2
2n=−6
Step 4: Divide both sides by 2.
2n -6
--- = ---
2 2
n=−3
It is not a mixed number because if you put the same number of the numerator on the denominator it would be a mixed number (1)
