Solve the Decimal Equation: Finding the Missing Value in 9.6 - ? = 7.4

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information - the equation is $9.6 - x = 7.4$.

• Step 2: Rearrange to isolate $x$ - add $x$ to both sides giving $9.6 = 7.4 + x$.

• Step 3: Subtract 7.4 from both sides to solve for $x$: $x = 9.6 - 7.4$.

• Step 4: Perform the subtraction: Calculate $9.6 - 7.4$.

Now, let's perform the calculation:
Performing the subtraction: $9.6 - 7.4 = 2.2$.

Therefore, the solution to the equation is $x = 2.2$.

The correct answer choice is $2.2$.
