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

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
