Question

The sum of three numbers is 91. The second number is 5 more than the first. The third number is 4 times the second

Answer 1

The first number:11

The second number: 16

The third number: 64

Explanation:

Let the first number be x

The second number be 5+x

The third number be 4(5+x)

The sum: x+5+x+4(5+x) =91

Open the brackets

x+5+x+20+4x=91

Arrange in like terms

x+x+4x+5+20=91

6x+25=91

6x=91-25

6x=66

Divde both sides by 6( the coefficient of x)

x=11

5+x=16

4(5+x) =64
