The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 3 x + 10$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = 10$$
Divide both parts of the equation by -5
We get the answer: x = -2
-2*(x+4) = 3*x+2
Expand brackets in the left part
-2*x-2*4 = 3*x+2
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 3 x + 10$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = 10$$
Divide both parts of the equation by -5
x = 10 / (-5)
We get the answer: x = -2
