Question

Tina solved an equation incorrectly, as shown below:

Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16

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

She did not divide 24 by 8.
She did not add 8 to 24.
She did not multiply 24 by 8.
She did not multiply 24 eight times

Answer 1

She did not divide 24 by 8.

Explanation:

Answer 2

Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16

Step 2 should be: x = 24 / 8
Step 3 would result to: x = 3

She did not divide 24 by 8.
