one number is 5 times a first number. a third number is 100 more than the first number. if the sum of the three numbers is 296296, find the numbers.

the first number is 28

the second number is 140

the third number is 128

Step-by-step explanation:

Let x represent the first number.

Let y represent the second number.

Let z represent the third number.

One number is 5 times a first number. This means that

y = 5x

A third number is 100 more than the first number. This means that

z = x + 100

If the sum of the three numbers is 296, it means that

x + 5x + x + 100 = 296

7x = 296 - 100

7x = 196

x = 28

y = 5x = 5 × 28

y = 140

z = x + 100 = 28 + 100

z = 128
