Question

5(х + 3) = – 2(1 – х) – 4

Answer 1

Ответ:

X=-7

Пошаговое объяснение:

1. Раскрываем скобки, умножая фонтанчиком

5x+15=-2+2x-4

2. Переносим х в одну сторону, числа в другую

5x-2x=-2-4-15

3.Решаем

3x=-21

x=-7

Answer 2

To solve the equation 5(x + 3) = -2(1 - x) - 4, follow these steps:

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

5x + 15 = -2(1) + 2x - 4

2. Simplify the equation by performing the multiplications and additions/subtractions:

5x + 15 = -2 + 2x - 4

3. Move the variable terms (those containing 'x') to one side of the equation by subtracting 2x from both sides:

5x - 2x + 15 = -2 - 4

3x + 15 = -6

4. Now, subtract 15 from both sides to isolate the variable term:

3x + 15 - 15 = -6 - 15

3x = -21

5. Finally, divide both sides by 3 to solve for 'x':

3x/3 = -21/3

x = -7

So, the solution to the equation is x = -7.
