The work of a student trying to solve the equation 4(2x – 1) = 11 + 3x + 5 is shown below:


Step 1: 4(2x – 1) = 11 + 3x + 5


Step 2: 8x – 4 = 16 + 3x


Step 3: 8x + 3x = 16 – 4


Step 4: 11x = 24


Step 5: x = 2.18


In which step did the student first make an error and what is the correct step? (4 points)



Step 2: 8x – 1 = 16 + 3x



Step 2: 8x – 8 = 6 + 3x



Step 3: 8x – 3x = 16 + 4



Step 3: 8x + 3x = 16 – 8

Verified Answer :

I hope this helps you



first step open parentheses





4.2x-4.1=11+3x+5


8x-4=16+3x



8x-3x=16+4



5x=20



5x÷5=20÷5


x=4



answer is step three it's must be 8x-3x
