Asked by jonathan1998

Answer (2)

6 4 x − 2 = 25 6 2 x ( 4 3 ) x − 2 = ( 4 4 ) 2 x 4 3 x − 6 = 4 8 x ⇔ 3 x − 6 = 8 x . 3 x − 8 x = 6 . − 5 x = 6 ⇔ x = − 5 6 ​

To solve the equation 6 4 x − 2 = 25 6 2 x , we rewrite both sides using the same base, leading to the equation 3 x − 6 = 8 x . Solving this gives us the final answer: x = − 5 6 ​ .
