Answer 1

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
