10/70 + 9/90 is 17/70.
1. Find the least common denominator or LCM of the two denominators:
LCM of 70 and 90 is 630
2. For the 1st fraction, since 70 × 9 = 630,
10/70 = 10 × 9/70 × 9 = 90/630
3. Likewise, for the 2nd fraction, since 90 × 7 = 630,
9/90 = 9 × 7/90 × 7 = 63/630 | HuggingFaceTB/finemath | |

1. Log(x-15)-2 = -Logx.
Log(x-15) + Logx = 2,
Log((x-15)x) = 2,
Exponential form:
(x-15)x = 10^2,
x^2 - 15x = 100,
x^2 - 15 -100 = 0,
(x+5)(x-20) = 0,
x+5 = 0,
X = -5.
x-20 = 0,
X = 20.
Solution set: X = -5, and X = 20.
