You can put this solution on YOUR website!
 
log2(5x + 2) = 4

Use the definition of a logarithm which states that the
logarithm equation log%28B%2CA%29=C is equivalent to the
exponential equation A=B%5EC.

Therefore your logarithm equation is equivalent to this
exponential equation:

5x + 2 = 24
5x + 2 = 16
    5x = 14
     x = 14%2F5 or 2.8
