Dylan solved the exponential equation 3x+1 = 15 and his work is shown below. what is the first step he did incorrectly?

step 1: log3x+1 = log15
step 2: 3 log(x + 1) = log15
step 3: log(x + 1) = log 15 over 3
step 4: log(x + 1) = 0.3920304
step 5: ln[log(x + 1)] = ln0.3920304
step 6: x + 1 = −0.936415
step 7: x = −1.936415
