Answer:
Step-by-step explanation:
"A number is [WHAT?] of another number." It appears the WHAT?? is missing. If it is a word such as "twice," it can be solved in this fashion.
Let the numbers be X and Y, with Y the larger number.
A number is twice another number: Y = 2X
The difference of the numbers is 18: Y - X = 18
Use the first equation (Y = 2X) in the second by replacing "Y" with (2X):
Y - X = 18
2X - X = 18
X = 18
Y = 2X, so Y = 36
