Question

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

Answer 1

the first mistake was in step 2

Step-by-step explanation: she should not have moved the y to the other side first, she should have moved the other numbers to get one of the y's alone
