The work of a student to solve the equation 3(2x − 4) = 8 + 2x + 6 is shown below: step 1: 3(2x − 4) = 8 + 2x + 6 step 2: 5x − 7 = 14 + 2x step 3: 5x − 2x = 14 + 7 step 4: 3x = 21 step 5: x = 7 in which step did the student first make an error and what is the correct step? step 2; 6x − 12 = 14 + 2x step 2; 6x − 7 = 2(6 + x + 4) step 3; 5x − 2x = 14 − 7 step 3; 5x + 2x = 14 + 7

The student made the error at step 2.

Step-by-step explanation:

The correct step will be:

Step 2; 6x − 12 = 14 + 2x

As 3 will be multiplied with 2x and 4 which will give 6x − 12

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
