Question

the difference between two numbers is 10 and their sum is four times the smaller number. find the two numbers

Answer 1

The smaller number is 5.

The bigger number is 15.

Explanation:

Let the smaller number be x and the bigger number be x+10.

x+x+10 = 4x

2x+10 = 4x

10 = 4x-2x

2x = 10

x = 10÷2

= 5

x+10 = 5+10

= 15
