Answer from: bryce2892

Step 3: 3x3 (Subtraction).

Step-by-step explanation:

1- Given the inequality shown in the problem, Zareen should solve it as following:

2-Subtract 4x from both sides:

7x + 5-4x  4x + 2 -4x\\3x+52

(Zareen did this step correctly)

3- Subtract 5 from both sides:

3x + 5-5  2-5\\3x-3

(As you can see, Zareen made a mistake in Step 3, because the subtraction is actually  2-5=-3)

4- Divide both sides by 3, then:

\frac{3x}{3}\frac{-3}{3}\\\\x-1
