Yes they are equivalent expressions. If you take the z to the power of two, and subtract that from the other z to the power of two, it is zero. So you are left with four which is the answer
Answer:

Step-by-step explanation:
We start by adding
to both sides, giving
, which after simplifying gives
.
We then add
to both sides, giving
, which after simplifying gives
.
We can then divide both sides by
, giving
, which after simplifying gives
, or
. So, x is 5.
1/3 x 4/4 = 4/12
4/12 + 5/12 = 9/12
12/12 - 9/12 = 3/12
3/12 = 1/4
