Question

The sum of numbers n and 4 is 17.​

Answer 1

$\huge\bold\red{Question}$

• The sum of numbers n and 4 is 17.

$\huge\bold\red{Solution}$

We will first form an equation out of the statement.we will first write n and then as a number has to be added to 4 we will put (+) sign after n and then 4.

As n+4 has to be equal to 17 we will put "=" sign after 4 and then we will finally put 17.

• $\small\bold\red{:}$$\red\implies$${\small{\red{\mathfrak{n+4=17}}}}$

Now as a constant needs to be on R.H.S. we will move +4 to R.H.S. by changing the sign from +4 to -4.

Now we will subtract 4 from 17

$\small\bold\red{:}$$\red\implies$${\small{\red{\mathfrak{n=17-4}}}}$

17-4 will give 13 as the difference.

$\small\bold\red{:}$$\red\implies$${\small{\red{\mathfrak{n=13}}}}$

$\huge\bold\red {Additional \: Information}$

$\text\color{red}{What \: is \: an \: expression?}$

• An expression is a combination of constants,variable and mathematical operations.

$\text\color{red}{Constants-}$A fixed value i.e.,any number , such as 1,2,56,100 are all constants because their values are fixed.

$\text\color{red}{Variable-}$ A non-fixed value i.e., any letter such as 'a,b,x,n' , etc are variable.

Answer 2

The sum of numbers n and 4 is 17 .

❥ n + 4 = 17

Explanation

n + 4 = 17

n = 17 - 4

n = 13
