Answer:


x= \frac{38}7

Step by step explanation:


~~~~~~~\log_(10) 7 + \log_(10)(x-4) = 1\\\\\implies \log_(10)(7(x-4)) = \log_(10) 10~~~~~~~~~~~~~~~;[\log_b(mn) = \log_b m + \log_b n]\\\\\implies 7(x-4) = 10\\\\\implies 7x -28 = 10\\\\\implies 7x = 10 +28 \\\\\implies 7x = 38\\\\\implies x= \frac{38}7
