Question

The sum of three numbers is 14. The largest is 4 times the smallest, while the sum of the smallest and twice the largest. Find the numbers

Answer 1

Step-by-step explanation:

let the unknown be x

4x+x+x=14

6x=14

x=14÷6

×=2.33333333....

Answer 2

Answer:

x=8

y=4

z=2

Step-by-step explanation:

let three no's. be x y and z

x+y+z=14

largest no. is 4 times smallest

x-4x=0

sum of smallest and twice largest is 18

2x+z=18

therefore, x+y+z=14 i

2x+0+z=18 ii

x+0-4z=0

solving the eqs

x=8,y=4,z=2
