Answer 1

In the expression x + 5 = 14, 'x' represents an unknown value and can be solved for by subtracting 5 from both sides of the equation. 'x' is equal to 9.

Step-by-step explanation:

In the expression x + 5 = 14, the variable 'x' represents an unknown value. It is a placeholder that we need to solve for in order to find its actual numerical value. In this equation, to isolate the variable 'x', we can subtract 5 from both sides of the equation:

x + 5 - 5 = 14 - 5

x = 9

Therefore, 'x' in the given expression is equal to 9.
