Question

if 243=3x, what is 3x-1​

Answer 1

Answer:

x=243/3=81

Now

3x-1=3×81-1=242

Answer 2

Given:

243=3x

To find:

3x-1

Solution:

We can find the solution by following the given process-

We know that the value can be obtained by substituting the value of x.

We have 3x=243

So, x=243/3

x=81

Now, on substituting the value of x, we get

3x-1=3×81-1

=243-1

=242

Therefore, the value of 3x-1 is 242.
