The sum of two number is 11 their diffrence is 5. what is the number?
The answer to this problem is the two numbers
The reason for this is because you have two unknowns, or variables, that add up to
So, we can deduce that the equation would be
Solving this would result in first adding five to both sides so that
and dividing both sides by two
So now we have the first term, and for the second term, you can do one of two things.
The first, understand that
The second way would be to plug it back into the equation so that
