$36^{x - 7} = 36$

Step 1

Create equivalent expressions in the equation that all have equal bases.

$36^{x - 7} = 36^{1}$

Step 2

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

$x - 7 = 1$

Step 3

Move all terms not containing $x$ to the right side of the equation.
