12x−3y
_______
4x−z

Answer 1

5

Explanation:

12x - 3y

------------

4x - z

Input the values provided:

12(3) - 3(1/3)

------------------

4(3) - 5

Start by simplifying the numerator and denominator expressions:

-numerator;

12(3) = 36

3(1/3) = 1

36 - 1 = 35

-denominator:

4(3) = 12

12 - 5 = 7

Then divide:

35

7

This will equal to 5, which is your final answer.
