Let one number = X and the second number = Y.
The sum of the numbers is 5 so you get X + Y = 5
One number exceeds the other by 11 ( that means the difference of the numbers is 11, so you would have X - Y = 11
Your two equations are:
X + Y = 5
X - Y = 11
Add the equations together:
x +x = 2x
y-y = 0
5+11 = 16
Now you have 2x = 16
Divide both sides by 2:
X = 16/2 = 8
Now you have x = 8, replace x with 8 and solve for Y:
8 + y = 5
Subtract 8 from both sides:
y = 5 - 8 = -3
X = 8, Y = -3
Answer and step-by-step explanation:
If we called the first number is x
The second number is y
We are given that:
x + y = 5
x = y + 11
Let put x from (2) into (1), we gotL
x + y = 5
y + 11 + y = 5
2y + 11 = 5
2y = 16
2y = 8
y = 8
Because y = 8 and x + y = 5 so:
x + 8 = 5
x = 5 - 8
x = -3
So x = -3 and y = 8 or x = 8 and y = -3
