Question

Maya solved an equation incorrectly, as shown below: Step 1: 4x = 28 Step 2: x = 28 – 4 Step 3: x = 24 Which statement best explains why Step 2 is incorrect in Maya's solution? (1 point)

A: She did not add 4 to 28.
B: She did not multiply 28 by 4.
C:She did not divide 28 by 4.
D:She did not multiply 28 four times.

Answer 1

Maya has to divide by 4, not subtract 4 C:She did not divide 28 by 4.

Answer 2

Option C - She did not divide 28 by 4.

Explanation:

Given : Maya solved an equation incorrectly, as shown below:

Step 1:
`4x = 28`

Step 2:
`x = 28 - 4`

Step 3:
`x = 24`

To find : Which statement best explains why Step 2 is incorrect in Maya's solution?

Solution :

First we solve the expression again to find the mistake.

Step 1:
`4x = 28`

Step 2:
`x = (28)/(4)`

Step 3:
`x = 7`

Thus, by the above steps it is clear that she did not divide 28 by 4 in step 2.

Therefore, Option C is correct.

The required statement that best explains her mistake in steps 2 is She did not divide 28 by 4.
