Answer:
x = -2/ 3
Step-by-step explanation:
in order to cancel out the logs they should have common bases

we can write 25 as 5²

we know that the reciprocal of the exponents of the bases are multiplied to the log

and now since the logs have common bases

we're left with


<u>x = -2/ 3</u>
Hello!


Begin isolating for x by subtracting 2 from both sides:

Further simplify by multiplying both sides by 3:

Multiply both sides by -1 to cancel out the -x:

The fraction is equivalent to 1/2 since you can simplify 4/8 as (4/4)/(8/4) = 1/2.
