Logarithms Algebra 2

Ashley solved the exponential equation 3x+1 = 15 and her work is shown below. What is the first step she did incorrectly?

Step 1: log 3^(x+1) = log15
Step 2: (x + 1)log 3 = log15
Step 3: x + 1 = log 15/log 3
Step 4: x+1 = 2.708050/1.098612
Step 5: x + 1 = 1.418858
Step 6: x = 0.418858
