Question

-3(2 - х) = 4(х + 9)

Answer 1

Ответ:

х = -42

Пошаговое объяснение:

-3(2 - х) = 4(х + 9)

-6 + 3х = 4х + 36

3х -4х = 36 + 6

-х = 42

х = -42

-3(2 - (-42) = 4 (-42 +9)

-3 · 44 = 4 · (-33) - верно

Answer 2

To solve the equation -3(2 - x) = 4(x + 9), you can follow these steps:

1. Distribute the constants on both sides of the equation:

-3 * 2 + 3x = 4x + 36

2. Simplify the equation:

-6 + 3x = 4x + 36

3. Move the variable terms (3x and 4x) to one side of the equation and the constant terms (-6 and 36) to the other side. You can do this by subtracting 4x from both sides and adding 6 to both sides:

3x - 4x = 36 + 6

-x = 42

4. Finally, to solve for x, multiply both sides of the equation by -1 to isolate x:

x = -42

So, the solution to the equation is x = -42.
