The work of a student to solve the equation 4(2x − 4) = 8 + 2x + 8 is shown below: step 1: 4(2x − 4) = 8 + 2x + 8 step 2: 6x − 8 = 16 + 2x step 3: 6x − 2x = 16 + 8 step 4: 4x = 24 step 5: x = 6 in which step did the student first make an error and what is the correct step? step 2; 8x − 4 = 2(6 + x + 6) step 2; 8x − 16 = 16 + 2x step 3; 6x − 2x = 16 − 8 step 3; 6x + 2x = 16 + 8

Step-by-step explanation:

Here, The work of a student to solve the equation :

The steps for calculating the value of x are :

Step 1: 4(2x − 4) = 8 + 2x + 8  

Step 2: 6x − 8 = 16 + 2x  

Step 3: 6x − 2x = 16 + 8  

Step 4: 4x = 24  

Step 5: x = 6

Step 2 is incorrect, as the student instead of multiplying, adds the number as :

4(2x − 4) = 8 + 2x + 8  

Here, the correct step is :

8x − 16 = 16 + 2x

6 x = 32

x = 5.33

So, the error is in STEP 2 and the correct option is (b).

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
