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