We need to simplify the next given expression:
We need to solve the like terms, "like terms" are terms whose variables and exponents are the same
Therefore, the like terms are:
7m and 8m
8z and -3z
5/12 and 4/12
Organize the expression:
Solving the like terms:
Finally, we can simplify the fraction 9/12 by 3/4 because 3*3 = 9 and
3*4 = 12
Then:
