The sum of two number is 77. If the first number is multiplied by 4 and the second is multiplied by 2, the sum is 286. What are the two numbers?

here 1st case

x+y=77

or, x=77-y

second case

4x+2y=286 (according to question)

putting value of x from first case

4 (77-y) + 2y=286

or, 308-4y+2y=286

or, 308-286=2y

or, 22=2y

or, 11=y and x=77-11

x=66

Step-by-step explanation:

so, y=11 and x=66
