Let represent the missing value (?). The equation can be written as:
Step 1: Perform the multiplication operations on both sides of the equation.
On the left-hand side:
On the right-hand side:
Substituting these values back into the equation gives:
Step 2: Simplify the right-hand side of the equation.
Now the equation is simplified to:
Step 3: Isolate by subtracting 640 from both sides.
