Final answer:
To solve the equation, subtract 4x from both sides and then add 9 to both sides.
Step-by-step explanation:
Let's represent the unknown number as x. The equation we can form from the given information is:
5x - 9 = 4x + 1
To solve for x, we can subtract 4x from both sides of the equation:
(5x - 4x) - 9 = 1
This simplifies to:
x - 9 = 1
Next, we can add 9 to both sides of the equation:
(x - 9) + 9 = 1 + 9
This simplifies to:
x = 10
Therefore, the value of the number is 1.0
