Chapter 15: Problem 2

Solve. $$ y+7=-3 $$

Short Answer

Expert verified
\( y = -10 \)

Step by step solution

01

- Isolate the variable y

The equation given is: \[ y + 7 = -3 \] To isolate the variable \( y \), subtract 7 from both sides of the equation.
02

- Perform the subtraction

Subtract 7 from both sides: \[ y + 7 - 7 = -3 - 7 \] which simplifies to \[ y = -10 \]
