\n 1.\u00a0Ciara solved the exponential equation 3x+1\u00a0= 15 and her work is shown below. What is the first step she did incorrectly?
\n
\n Step 1:
\n <\/b>
\n log 3x+1\u00a0= log15
\n
\n Step 2:
\n <\/b>
\n (x + 1)log 3 = log15
\n
\n Step 3:
\n <\/b>
\n log3 =

\n Step 4:
\n <\/b>
\n 0.477121 =
\n
\n Step 5:
\n <\/b>
\n 0.477121(x + 1) = 1.176091
