Answer:

x = 4, y = 6, z = 8

Step-by-step explanation:

x + y = 10

y + z = 14

x + y + z = 18

z = (x + y + z) - x - y

  = 18 - 10

z = 8

y = (y + z) - z

  = 14 - 8

y = 6

x = (x + y) - y

  = 10 - 6

x = 4

What is 9 5/6 - 2 1/3
Mariana [72]
9 5/6 - 2 1/3 is 7 1/2.

You could get this answer by finding the same denominator of the fractions. The LCM of both is 6. Multiply the 1 of the second fraction 2 times because you had to multiply the denominator 2 times to get to 6. 
You should have 2 2/6.

Now get 9 5/6 - 2 2/6.

The answer is 7 3/6, simplifies into 7 1/2.
9 5/6 - 2 1/3 is 7 1/2.
