The work of a student to solve the equation 2(5y − 2) = 12 + 6y is shown below: step 1: 2(5y − 2) = 12 + 6 step 2: 7y − 4 = 12 + 6 step 3y − 4 = 10step 4: y = 14step 5: y = 7in which step did the student first make an error and what is the correct step

Error in step 2

Step-by-step explanation:

equation

Given steps:

step 1: 2(5y − 2) = 12 + 6

step 2: 7y − 4 = 12 + 6

step 3y − 4 = 10

step 4: y = 14

step 5: y = 7

In step 2 , 2 is distributed inside the parenthesis. When we multiply 2 inside the parenthesis 2 times 5y is 10y

Instead of multiplying , the student added 2 and 5y and got 7y

So the error is in step 2

Step 2 should be

8y^50
