Answer 2

To solve the equation log₁.₇(2 - 5x) = log₁.₇(21), you can use the property of logarithms that states that if the bases of the logarithms are the same, then the arguments inside the logarithms must be equal. In this case, both logarithms have a base of 1.7, so:

2 - 5x = 21

Now, you can solve for x:

2 - 5x = 21

Subtract 2 from both sides:

-5x = 21 - 2

-5x = 19

Now, divide by -5 to solve for x:

x = 19 / -5

x = -19/5

So, the solution for the equation is:

x = -19/5
