Question 675092
let x = the lesser number
the greater number is 3 more than twice the lesser number
twice the lesser number is 2x
3 more would be 2x+3
the greater number plus the lesser number = 9
x+2x+3=9
combine like terms
3x+3=9
subtract 3 from both sides
3x=6
divide both sides by 3
x=2

answer:  the lesser number is 2 and the greater number is 2x+3  2(2)+3
4+3=7    so the greater numer is 7

check answer: 2+2x+3=9
2+2(2)+3=9
2+4+3=9
9=9
