Deshaun's equation is \( a + 7 = 52 \), where \( a \) represents Adele's age. To solve for \( a \), the next step would be to isolate \( a \) by removing the 7 from the left side of the equation.
The correct next step is:
**D. He subtracts 7 from both sides of the equation.**
This would lead to:
\[ a + 7 - 7 = 52 - 7 \]
Which simplifies to:
\[ a = 45 \]
So, Adele is 45 years old.
The correct next step is:
**D. He subtracts 7 from both sides of the equation.**
This would lead to:
\[ a + 7 - 7 = 52 - 7 \]
Which simplifies to:
\[ a = 45 \]
So, Adele is 45 years old.
