Question

The sum of three numbers 157. The third number is 7 less than the firstThe second number is 4 times the third What are the numbers?

Answer 1

Explanation:

Let the first number be = x

Let the second number be = 4x -28

Let the third = x-7

x + 4x+ x -28 - 7

6x - 35

6x -35 = 157

6x = 157 +35

6x = 192

x = 32

therefore, x = 32, the second x = 4(32) -28

728 - 28

x = 100

third x = 32 - 7

x = 25.
