To solve the equation 3636:(12x-91)=36, we need to isolate the variable x.

First, let's simplify the equation:

3636 / (12x - 91) = 36

Now, let's cross multiply:

3636 = 36 * (12x - 91)

Next, distribute the 36:

3636 = 432x - 3276

Now, let's isolate the variable x by moving the constant term to the other side:

3636 + 3276 = 432x

6912 = 432x

Finally, divide both sides by 432 to solve for x:

x = 6912 / 432

x ≈ 16

Therefore, the solution to the equation 3636:(12x-91)=36 is x ≈ 16.
