-3x+2(x+2)=4(-x-3)-1 — step-by-step solution

Let's solve in

ℝ

- 3 x + 2 \cdot (x + 2) = 4 \cdot (- x - 3) - 1

ℹ

2 \cdot (x + 2)

2 x + 4

‖

4 \cdot (- x - 3)

4 \cdot (- x) - 12

- 3 x + (2 x + 4) = (4 \cdot (- x) - 12) - 1

ℹ

- 3 x + 2 x

- x

‖

- 12 - 1

-13

- x + 4 = - 4 x - 13

- x = - 4 x - 17

- x + 4 x = -17

3 x = -17

▶Solution found:

x = - \frac{17}{3}

The numeric value of:

x = - \frac{17}{3}

equals:

▷

x = \approx -5.6667
