l o g ( 10 − 4 x ) = l o g ( 10 − 3 x ) ⟺ 10 − 4 x = 10 − 3 x − 4 x + 3 x = 10 − 10 − x = 0 / ⋅ ( − 1 ) x = 0 ∈ D S o l u t i o n : x = 0

The solution to the equation lo g ( 10 − 4 x ) = lo g ( 10 − 3 x ) is x = 0 . This solution is valid as it falls within the domain constraints of the logarithmic functions involved. Thus, this is the only solution.

Jawaban-15 - (-35) = -15 + 35 = 20PembahasanDalam operasi pengurangan bilangan bulat, jika pengurang adalah bilangan negatif, maka operasi tersebut berubah menjadi operasi penjumlahan dan pengurang berubah menjadi bilangan positif.Misalnya,10 - (-7) = 10 + 7 = 17-72 - (-12) = -72 + 12 = -60-38 - (-59) = -38 + 59 = 21Semoga membantu
