Step 1
We have given the problem :
3n122n+37=1
We have to state whether it an equation or an expression ,if it an equation then we have to solve it and if it an expression then we have to simplify it .
Step 2
We have :
3n122n+37=1...(1)
We know that in an equation there is an = sign which makes LHS and RHS equal .
In an expression there is no = sign.
Observe that in (1) is involved with LHS and RHS and they are equated with the sign =.
So (1) is an equation and we will solve it.
3n122n+37=1
7(3n1)2(2n+3)14=1
21n74n614=1
17n1314=1
17n−13=14
17n=14+13
17n=27
n=2717
So the required solution is n=2717
