The solution

You have entered [src]
-2*x - 4 = 3*x
$$- 2 x - 4 = 3 x$$
Detail solution
Given the linear equation:
-2*x-4 = 3*x

Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 3 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$- 5 x = 4$$
Divide both parts of the equation by -5
x = 4 / (-5)

We get the answer: x = -4/5

x1 = -4/5
$$x_{1} = - \frac{4}{5}$$
Sum and product of roots [src]
sum
0 - 4/5
$$- \frac{4}{5} + 0$$
=

$$1 \left(- \frac{4}{5}\right)$$
=
-4/5
$$- \frac{4}{5}$$
-4/5
