Question

2. Решите уравнение: 2(3 – х) + 7х = 4 – (3х + 2).

Answer 1

2(3 – х) + 7х = 4 – (3х + 2).
6 – 2х + 7х = 4 – 3х - 2
– 2х + 7х +3x= 4-2-6
8x=-4
x= - 0,5

Answer 3

I can help you solve this equation. Here are the steps:

- First, we need to simplify the equation by removing the parentheses and combining the like terms. We get:

$$2(3 - x) + 7x = 4 - (3x + 2)$$ $$6 - 2x + 7x = 4 - 3x - 2$$ $$5x + 8 = -3x + 2$$

- Next, we need to isolate x on one side of the equation by adding or subtracting the same term on both sides. We get:

$$5x + 8 + 3x = -3x + 2 + 3x$$ $$8x + 8 = 2$$

- Then, we need to divide both sides by the coefficient of x, which is 8. We get:

$$\frac{8x + 8}{8} = \frac{2}{8}$$ $$x + 1 = \frac{1}{4}$$

- Finally, we need to subtract 1 from both sides to get the value of x. We get:

$$x + 1 - 1 = \frac{1}{4} - 1$$ $$x = \frac{1}{4} - \frac{4}{4}$$ $$x = -\frac{3}{4}$$

- Therefore, the solution of the equation is $$x = -\frac{3}{4}$$.
