One number is 4 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 256 f
Lady bird [3.3K]

Answer: one number is 104, the first number is 26 and the third number is 126

How to:

Let’s say the “first number” is Y, the “second number” is X, and the “third number” is Z. This makes Y=4x and Z=x+100. Then put it into an equation to find the sum: X+4x+x+100=256. Take away 100 from both sides of the equation and combine the like terms (the X’s). That leaves 6x=156. Then divide both sides by 6 to get x alone which is x=26. That is the first number. To find Y just multiply X by 4 and that’s Y=104. And lastly add 100 to x which is Z=126.
