First equation:
2^3 (x-7) = 2^4 198 (x-7) = 16 198x - 56 = 3048x = 360x = 45
Second equation:
(4x-13) 7 = 7^2(445 - 13) 7 = 49(180 - 13) 7 = 49167 * 7 = 491169 = 49
So the solutions are x = 45 and 1169.
First equation:
2^3 (x-7) = 2^4 19
8 (x-7) = 16 19
8x - 56 = 304
8x = 360
x = 45
Second equation:
(4x-13) 7 = 7^2
(445 - 13) 7 = 49
(180 - 13) 7 = 49
167 * 7 = 49
1169 = 49
So the solutions are x = 45 and 1169.
