Final Answer:

After solving b - 18 = a the answer is
\[ b = a + 18 \]

Step-by-step explanation:

In the given equation b - 18 = a , we want to solve for b . To isolate b , we need to get rid of the constant term (-18) on the left side of the equation. The inverse operation of subtracting 18 is adding 18. By adding 18 to both sides of the equation, we can cancel out the -18 on the left side, leaving us with b on its own. Therefore, b = a + 18 .

Now, let's go through the solution step by step. Starting with the original equation b - 18 = a , we add 18 to both sides:


\[ b - 18 + 18 = a + 18 \]

On the left side, the -18 and +18 cancel out, leaving us with b . On the right side, we have a + 18 . Therefore, the solution is b = a + 18 .

This result makes sense intuitively; if we have a value a and we add 18 to it, we get the value of b . So, in summary, to solve for b in the equation b - 18 = a , we add 18 to both sides, yielding b = a + 18 .
