Question 80221
{{{x/12+9x/12}}}
These are like terms - i.e. the powers of x are the same in each term. As a bonus, they also have the same denominator. So just add them up.
{{{10x/12}}}
Now you can reduce this by recognizing that the numerator and denominator are divisible by 2:
{{{highlight(5x/6)}}}
Good Luck,
