Uhm i’m sorry but there isn’t an image
X=-8/z-2y...
z=2y-8/x...
y=xz/2+4
Answer:
2 2/4
Step-by-step explanation:you first see how many times the bottom number goes into the top number, then you put the remainder in a fraction!!
Answer:

Where z = 3m-2n
Step-by-step explanation:
An important mathematical property about the powers is that when powers of equal base are divided, the same base is placed and the exponents are subtracted.
Then we can write 1000m and 100n as powers of the same base:

Now we perform the division of powers of the same base (10)

Finally

Where z = 3m-2n
