Ciara solved the exponential equation 3x+1 = 15 and her work is shown below. what is the first step she did incorrectly?
step 1: log 3x+1 = log15
step 2: (x + 1)log 3 = log15
step 3: log3 = log 15 over x plus 1
step 4: 0.477121 = 1.176091 over x plus 1
step 5: 0.477121(x + 1) = 1.176091
step 6: x + 1 = 1.176091 over 0.477121
step 7: x + 1 = 2.464975
step 8: x = 1.464975
(i think it is step 3)
