Final answer:
To solve the equation 19 + n = 30, subtract 19 from both sides to isolate n, resulting in n = 11 as the solution.
Step-by-step explanation:
To solve the equation 19 + n = 30, you want to find the value of n that makes the equation true. To do so, you need to isolate n on one side of the equation. Begin by subtracting 19 from both sides of the equation to maintain equality:
19 + n - 19 = 30 - 19
This simplifies to:
n = 11
So, the solution to the equation is n = 11.
