Question

Slove the equation given below 3n+1=5
​

Answer 1

An(i) x + 3 = 0

By putting x = 3

L.H.S. = 3 + 3 = 6 ≠ R.H.S.

Hence, the equation is not satisfied.

(ii) x + 3 = 0

By putting x = 0

L.H.S. = 0 + 3 = 3 ≠ R.H.S.

Hence, the equation is not statisfied.

(iii) x + 3 = 0

By putting x = – 3

L.H.S. = – 3 + 3 = 0 = R.H.S.

Hence, the equation is satisfieds

Answer 2

Answer:

We will get the value of n$=\frac{3}{4}$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question  3n+1=5

​  We have find the value of" n" in the above question.

Here we will use the transposition method.

Hence, for solving the above equation, we will solve it by separating the like terms at one side ,  

So, we will shift 1 from LHS to RHS the sign will change from positive to negative,

As we get,

$3n+1=5\\3n=5-1\\3n=4$

Dividing both side by $3$ we get,

$\frac{3n}{3} =\frac{4}{3} \\n=\frac{4}{3}$

Hence we get the value of n=$\frac{3}{4}$
