Question

(07.01 MC) 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) She did not divide 28 by 4. She did not multiply 28 four times. She did not add 4 to 28. She did not multiply 28 by 4.

Answer 1

She did not divide 28 by 4

Answer 2

She did not divide 28 by 4

Explanation:

Here, the given expression is,

4x = 28,

The step involve in solving this expression are as follows,

Step 1 :
`4x=28`

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

Step 3 :
`x = 7`

Thus, by the above steps it is clear that she should divide both sides by 4 for isolating x on left side,

Hence, the required statement that best explains her mistake in steps 2 is,

'She did not divide 28 by 4'
