exponents

I've got a problem which I am not sure of the method of solving.

3x + 36 x 2 = 37

3x + 729 x 2 = 36 x 3

3x + 1458 = 729 x 3

3x = 2187 - 1458

3x = 729

3x = (3)6

x = 6

But isnt there any other method of solving? Please help

Since 37 = 36 x 3 ,

3x = (36 x 3) - (36 x 2) = 36[3 - 2] = 36

So x = 6

3x + 36 x 2 = 37

3x= 37 - 36 x 2

3x= 36 [3- 2] = 36

x=6

Does this make life simpler?
