Question

If x = y – 3 and y = z + 7, then x (in terms of z) = ?

Answer 1

Let's convert all into one variable and then do lcm of them. So, this is the simplest method

Step 1:

X = 3y/4

Z = 7y/6

x:y:z = 3y/4 : y : 7y/6

x:y:z = 3/4 : 1 : 7/6

Do lcm of 4 and 6 it's 12 .so, multiply with 12.

x:y:z = 9:12:14
