l o g 11 121 1 = − x − 4 l o g 11 1 1 − 2 = − x − 4 1 1 − x − 4 = 1 1 − 2 − x − 4 = − 2 − x = − 2 + 4 − x = 2 x = − 2
The solution to the equation lo g 11 121 1 = − x − 4 is x = − 2 . We arrived at this solution by rewriting the logarithm in terms of its base and isolating x through algebraic manipulation.
