Respuesta :
all you would do is minus what you have, like 11-3= 8 which would be 8+3=11 and 11-8=3 which means now you have the sum of 11 and the difference of 3.
The two numbers are 7 and 4
Let the first number = x
let the second number = y
The sum of the numbers is 11, in algebra form x + y = 11
The difference of the two numbers is 3, in algebra form, x - y = 3
To obtain the two unknown numbers, we solve the two equations;
from the first equation, x = 11 - y
substitute the value of x into the last equation;
(11 - y) - y = 3
11 - y - y = 3
11 - 2y = 3
2y = 11 - 3
2y = 8
y = 4
The value of x = 11 - 4 = 7
Thus, the two numbers are 7 and 4
