Let's solve the equation step by step:
-
Start with the original equation: \[ 8a + 18 = 18 \]
-
Subtract 18 from both sides: \[ 8a = 18 - 18 \] \[ 8a = 0 \]
-
To find \( a \), divide both sides by 8: \[ a = \frac{0}{8} \] \[ a = 0 \]
So, the completed process looks like this:
- \( 8a + 18 = 18 \)
- \( 8a = 0 \)
- Subtract 18 from both sides.
- \( a = 0 \)
- Divide both sides by 8.
