Question

A NUMBER IS EIGHT MORE THAN THREE TIMES OF THE OTHER NUMBER .IF THEIR SUM IS 12.FIND THE NUMBERS

Answer 1

let 3x+8 and 3x be the first and second number respectively

by question

3x+8 + 3x = 12

3x+3x+8=12

6x+8=12

6x=12-8

6x=4

x=4/6

x=⅔

then,

first number=3x+8 = 3×⅔+8 = 2+8 = 10

the second number = 3x= 3×⅔ = 2

checking

10+2=12
