Answer:
X = 19
Explanation:
To solve the equation X + 40 = 59, we need to isolate the variable X on one side of the equation.
1. Start by subtracting 40 from both sides of the equation:
X + 40 - 40 = 59 - 40
This simplifies to:
X = 19
2. Therefore, the value of X that satisfies the equation is 19.
In summary, to solve the equation X + 40 = 59, you subtract 40 from both sides of the equation to isolate the variable X. This results in X = 19.
