Answer:

Hey there! to answer your question, let me tell you what is an equation.

What is an equation?

Ans. An equation is 2 or more terms that have an equal to(=) sign.

What is a term?

Ans. A term is nothing but parts of the equation.

There are 4 main types of terms.

they are:

1. Monomial: This is only one single term. Eg: 1ab.

2. Binomial: These are 2 terms. For eg: 1ab+4a

3. Trinomial: These are 3 terms. For eg: 1ab+4a+3df

4. Polynomial: these are terms with 1 or more terms. so, a monomial, binomial and trinomial are all polynomials. Eg: 1ab+4a+3df+46dg

Step-by-step explanation:

So, following the meaning of an explanation and equation, let us answer your question:

Q. The sum of the digits in a 2 digit number is 11. If 9 is subtracted from the number, the places of the digits get interchange. find the number.

Ans. So, first let us form an equation for the above question.

Equation= let the numbers be x and y.

x+y=11

So, let us find the possible numbers that add up to 11.

They are:

10+1

11+0

9+2

8+3

7+4

6+5

So, let us subtract 9 from each of the numbers when they are put togheter as a number and see if the numbers get interchange when subtracted.

10,1=11-9=2, not equal to 11( interchanged number of 11)

11,0=11-9=2, not equal to 11( interchanged number of 11)

9,2=92-9=83, not equal to 29( interchanged number of 92)

8,3=83-9=74, not equal to 38( interchanged number of 83)

7,4=74-9=65, not equal to 47( interchanged number of 74)

But,

6,5=65-9=56, equal to 56( interchanged number of 65)

So, the number is 65.
