(х÷(-2)+4,5)÷(-1,5)=3​

0,5x+4.5÷(-1.5)=3

0.5x+3=3

0.5x=0

x=0

Answer 2

To solve the given expression, let's break it down step by step:

1. Begin with the innermost parentheses: (х ÷ (-2) + 4.5)

2. Solve the division first: х ÷ (-2) = -0.5x

3. Substitute the result back into the expression: (-0.5x + 4.5) ÷ (-1.5)

4. Now, solve the division: (-0.5x + 4.5) ÷ (-1.5) = -0.5x/(-1.5) + 4.5/(-1.5) = (0.5x/1.5) - (4.5/1.5)

5. Simplify further: (0.5x/1.5) - (4.5/1.5) = (0.5/1.5)x - (3/1.5)

6. Continue simplifying: (0.5/1.5)x - (3/1.5) = (1/3)x - 2

Now we have the expression simplified as (1/3)x - 2. To determine when this expression equals 3, we can set it equal to 3 and solve for x:

(1/3)x - 2 = 3

Add 2 to both sides: (1/3)x = 5

Multiply both sides by 3 to isolate x: x = 15

Therefore, the value of x that satisfies the given expression is x = 15.
