Answer:

Step 1

Step-by-step explanation:

Step 1 is incorrect because he forgot to use the distributive property.
Step 1 is incorrect






Explanation:

1/2 (2h - 4) = 20 needs to be distributed.
1/2 * 2h = 1h and 1/2 * -4 = -2 and 20 * 1/2 = 10

It should be 1h - 2 = 10

But since he didn’t distribute, his first step was wrong causing the whole problem to be incorrect.
