Question

the difference of two numbers is 5. the sum of three times the larger number and twice the smaller number is 30. what is the smaller number

Answer 1

smallest number=3

Explanation:

let the numbers be x & y and x>y

x-y=5

multiply by 2

2x-2y=10

and 3x+2y=30

adding

5x=40

x=40/5=8

8-y=5

y=8-5=3
