Решить уравнение 4х-9=8х+5Варианты ответов:  3 -3,5 -3

Answer 1

4х-8х=9+5
-4х=14
х=-3,5

Answer 2

To solve the equation 4x - 9 = 8x + 5, follow these steps:

Step 1: Combine like terms: Move the variable terms to one side of the equation and the constant terms to the other side: 4x - 8x = 5 + 9

Step 2: Simplify: -4x = 14

Step 3: Isolate the variable: To solve for x, divide both sides of the equation by -4: x = 14 / -4

Step 4: Calculate the result: x = -7

The correct answer is x = -7. None of the provided answer options (3, -3.5, -3) is correct.
