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.

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.

Step 2.

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.
