Question

The sum of the two numbers is 16. One number is 4 less than 3 times the other. Find the numbers.

Answer 1

5 and 11

Explanation:

Make equations:

x+y = 16

3x-4 = y

Substitute 3x-4 as y in x+y = 16

You get x + 3x - 4 = 16

Simplify into 4x - 4 = 16

Add 4 on both sides

you get 4x = 20

Divide each side by 4,

You get x = 5. Plug 5 back into x+y = 16

Subtract 5 from both sides, and you get y = 11
