1. The equation is -2 + y = 10.
2. To isolate y, you need to perform the inverse operation of subtracting 2, which is adding 2.
3. Add 2 to both sides of the equation.
4. -2 + y + 2 = 10 + 2
5. y = 12
Full Answer
y = 12
The equation is -2 + y = 10.
To solve for y, we need to isolate it on one side of the equation.
We can do this by adding 2 to both sides:
-2 + y + 2 = 10 + 2
y = 12
Common mistakes
✗ Subtracting 2 from both sides instead of adding.
✗ Making a mistake with the negative number, e.g., 10 - 2 = 8.
