Answer:

I do not understand she question do you mean the sum of their income is 2640

if so, then the answer is 440 to be x income

Step-by-step explanation:

x income = 20% or 1/5 of y income

y income = 5 of x income

we know that the sum of their income = 2640

which means that

x + y = 2640 =

1/5y + y = 2640

6y/5 = 2640

cross multiply to give us

6y = 5(2640)

6y = 13200

divide through by 6 to give us,

6y/6 = 13200/6

y = 2200

since we know that x income is 20% y income,

therefore, x income =

20/100 * 2200

= 440

therefore,

x income = 440

y income = 2200

Answer:

  • 1440

Step-by-step explanation:

The equations to reflect the given:

  • x + y = 2640
  • x = y + 20% ⇒ x = 1.2y

Substitute the value of x into first equation and solve for y:

  • 1.2y + y = 2640
  • 2.2y = 2640
  • y = 2640/2.2
  • y = 1200

Find x:

  • x = 2640 - 1200 = 1440
