To solve the equation \( \frac{1}{4}(x + 3) = 5 \), we can fill in the spaces as follows:
Step 1: Multiply both sides by 4.
\( 4 \cdot \frac{1}{4}(x + 3) = 4 \cdot 5 \)
So it becomes: \( (4) \frac{1}{4}(x + 3) = 20 \).
Step 2: Simplify the left side.
On simplifying, we get:
\( x + 3 = 20 \).
Step 3: Subtract 3 from both sides.
So, the equation becomes:
\( x + 3 - 3 = 20 - 3 \).
Step 4: Solve for x.
This simplifies to:
\( x = 17 \).
Putting it all together:
- \( 4 \cdot \frac{1}{4}(x + 3) = 20 \)
- \( x + 3 = 20 \)
- Subtract 3 from both sides.
- \( x = 17 \)
