Answer: B) Step 2

Explanation:

Step 1 is correct. She subtracted 7 from both sides. That's why the 12 becomes 12-7 = 5.

Her step 2 is not correct because she should have multiplied both sides by 5. The correct step 2 should look like 2n = 25. Then after this, she should divide both sides by 2 to get n = 25/2 = 12.5

Answer:

12.5

Step-by-step explanation:

Step 2

When working out 2/5n = 5

Jamie did not use the process of KCF, or KEEP, CHANGE, FLIP

They proceeded with dividing 2/5 by 5, but did not flip the 2/5 to 5/2, which then gave them the answer of 2

5 ÷ 2/5 = 5 x 5/2 = 25/2 = 12.5

12.5 is the final answer
