Debbie finished her algebra test early so she decided to check each of her answers. After checking her answer to question #10, she realized she made a mistake in her solution. In which step does Debbie make her mistake?

Original Equation: 2 + 3y = 5(y - 2)

Step One: 2 + 3y = 5y - 10

Step Two: 2 = 2y - 10

Step Three: -8 = 2y

Step Four: -4 = y ¨ y = -4

1

2

3

4

Step 2: because instead of adding the like terms he subtracted them

Step 1 & 2 are right. She made the first mistake in Step 3, it should be

2 + 10 = 2y

12 = 2y

And so the succeeding steps are wrong too. But the earliest was in step 3.

hope this helps :3
