Penjelasan dengan langkah-langkah:

^7log(5x + 3) = ^7log(3x – 1)

         5x + 3 = 3x – 1

       5x – 3x  = -1 – 3

              2x  = -4

                x = -4/2

                x = -2

⁷log (5x + 3) = ⁷log (3x − 1)

x = …?

jawaban :

5x + 3 = 3x – 1

5x – 3x = -1 – 3

2x = -4

x = -4 / -2

x = 2
