Mona solved an equation incorrectly, as shown below:


Step 1: 5x = 30

Step 2: x = 30 − 5

Step 3: x = 25


Which statement best explains why Step 2 is incorrect in Mona's solution?


She did not add 5 to 30.


She did not divide 30 by 5.


She did not multiply 30 by 5.


She did not multiply 30 five times.

Verified Answer :

Mona subtracted 5 where she should have divided 5. If the equasion was. x+5=30 then she would have subtracted 5.

Answer:

Option 2nd is correct

She did not divide 30 by 5.

Step-by-step explanation:

As per the statement:

Mona solved an equation incorrectly, as shown below:

Step 1: 5x = 30

Step 2: x = 30 − 5

Step 3: x = 25

Step 2 is incorrect as she did not divide 30 by 5.

Correct steps for the equation are:

Step 1.

\(5x = 30\)

Step 2.

\(x = \frac{30}{5}\)

Step 3.

x = 6

Therefore, the statement which explains that Step 2 is incorrect in Mona's solution is, She did not divide 30 by 5.
