Question 993564
Mary gave her money to Danny. We'll call her money x
Danny must come up with $5 less than 2x, this is, 2x-5. Finally:
x+2x-5= 70 add 5 on both sides
x+2x= 75 Add x on left
3x= 75 Divide both sides by 3
x= 25 This is how much money Mary gave Danny. So, Danny must come up with:
25*2-5= 50-5= 45 This is the amount Danny must come up with. Let's see if it's true:
25 Mary + 45 Danny = 25+45= 70 We've got the right answer.
