Question

1. Find N. if 3 + 2N = 9 – N. *


pls answer fast and right

Answer 1

Answer:

N is 2.

Step-by-step explanation:

if N is 2 then=3+2*2=9-2

=3+4=9-2

=7=9-2

=7=7

so N is 2.

Answer 2

Answer:

The required value of n $=2$

Step-by-step explanation:

As per the data in given equation

In above question it is given that

We have find the value of given expression

Given the data in question  3 + 2N = 9 – N.

We have find the value of" N" in above equation

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 to other side  

So, we will shift 3 from LHS to RHS the sign will change from positive to negative,

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

As we get,

$3+2n=9-n\\2n+n=9-3\\3n=6$

Divide both side by 3 we get,

$\frac{3n}{3} =\frac{6}{3} \\n=2$

Hence the required value of n$=2$
