Answer 3

Solving the Equation [x+2,5]=1

To solve the equation [x+2,5]=1, we need to understand the notation used in the equation. The notation [x+2,5] typically represents an interval or a range of values. In this case, it seems to denote a range of values from x+2 to 5. The equation then sets this range equal to 1.

Interpreting the Equation

The equation [x+2,5]=1 can be interpreted as finding the values of x that satisfy the condition where the range from x+2 to 5 is equal to 1.

Solution Approach

To solve for x, we can approach this by considering the range [x+2,5] and finding the values of x that make this range equal to 1.

Solution Steps

1. Subtract 2 from both sides of the equation to isolate the range [x,5]. 2. Set up the inequality x ≤ 3, as the range [x,5] should equal 1. 3. Therefore, the solution to the equation [x+2,5]=1 is x ≤ 3.

This approach considers the range notation and the condition set by the equation to find the values of x that satisfy the given equation.
