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

Option B

Step 2:

Step-by-step explanation:

We are given that an equation

We are given steps which are solved by student .We have to find the first  error he makes in her/his  steps and correct it.

Step1:

Step 2:

But student did in step 2:

So , he makes error in step 2

Step 3:

Step 4:

Step 5:

Hence, option B is true , step 2:

range is infinite on both x and y axis positive and negative

step-by-step explanation:

the answer is 99.
