Question

the some of two number is 80. The larger number exceed four time the smaller one by 5. Find the numbers.

Answer 1

Answer:

The numbers are 15 and 65

Step-by-step explanation:

Let one of the numbers be x and the other be 80-x

80-x=4x+5

5x=75

x=15

80-x=65

Answer 2

Step-by-step explanation:

let the larger no be x

and the smaller be y

acc to condition x+ y = 80 , x =80 - y

and 4x + 5 = y

4 (80- y ) +5 = y

320 - 4y +5 = y

325 = y + 4y

325 = 5y.

325/ 5 = y

65 = y

thus x = 80 - y

x = 80 - 65

x = 15
