Answer:

22

Explanation:

Let the first number be x.

Let the second number be y.

(x+y)/2 = 11

x-y=4

Solve for x in the second equation.

x = 4 + y

Put x as 4 + y in the first equation and solve for y.

(4+y+y)/2 = 11

4 + 2y = 22

2y = 18

y = 9

Put y as 9 in the second equation and solve for x.

x = 4 + 9

x = 13

Find the sum of the numbers x and y.

x + y

13 + 9

= 22

Answer:


22

Explanation:

let the numbers be x and y


(x + y)/(2) = 11 \\ x - y = 4

so,


(x + y)/(2) = 11 \\ x +y = 11 * 2 \\ x + y = 22

So they asked to find the sum of the two numbers

And the answer is 22
