To solve the equation \( b + 4 = 21 \), the steps to take are as follows:
1. **Subtract 4 from both sides of the equation.**
- This simplifies the equation to \( b = 21 - 4 \).
2. **The answer is \( b = 17 \).**
3. **Check the solution by substituting 17 for \( b \).**
- Substitute \( 17 \) back into the original equation: \( 17 + 4 = 21 \), which is a true statement.
Therefore, the correct response is:
1. Subtract 4 from both sides of the equation.
2. The answer is \( b = 17 \).
3. Check the solution by substituting 17 for \( b \).
1. **Subtract 4 from both sides of the equation.**
- This simplifies the equation to \( b = 21 - 4 \).
2. **The answer is \( b = 17 \).**
3. **Check the solution by substituting 17 for \( b \).**
- Substitute \( 17 \) back into the original equation: \( 17 + 4 = 21 \), which is a true statement.
Therefore, the correct response is:
