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 = log15Step 2: (x + 1)log 3 = log15Step 3: log3 = log 15 over x plus 1Step 4: 0.477121 = 1.176091 over x plus 1Step 5: 0.477121(x + 1) = 1.176091Step 6: x + 1 = 1.176091 over 0.477121Step 7: x + 1 = 2.464975Step 8: x = 1.464975A. Step 1B. Step 2C. Step 3D. Step 4
