I'm thinking of two numbers one of them is 11 more then the other and their sum is 131 what are the numbers

71 and 60

Step-by-step explanation:

Let the numbers be A and B

Given one of the number is 11 more than the other,

That's

A = B + 11

And their sum is 131

That's

A + B = 131

We now have two expressions

A = 11 + B and

A + B = 131

Now, substitute B + 11 for A into the second expression.

We have

A + B = 131

11 + B + B = 131

11 + 2B = 131

Subtract 11 from both sides

11 - 11 + 2B = 131 - 11

2B = 120

Divide both sides by 2

B = 120/2

B = 60

Substitute 60 for B in either expressions to get A

Using the first expression, we have

A = 11 + B

A = 11 + 60

A = 71

The numbers are 71 and 60
