Given

Required
Evaluate 
We have:

Apply law of logarithm

Express 9 as 3^2

Evaluate the exponents

.
So:


Substitute 


Your answer is x = 3 because if you take 150 and subtract it by both sides:
150 - 35x = 45
-150 -150
you have to cross out both 150 and -150, take 45 and subtract 150 which will give you -105.
-35x = -105
take -35 and divide by both sides. Cross out the two -35's. Take -105/-35 which your answer is x = 3. Hopes this helps. :)
