The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = - 11 x - 10$$
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
4*x+5*(3-2*x) = 5-11*x
Expand brackets in the left part
4*x+5*3-5*2*x = 5-11*x
Looking for similar summands in the left part:
15 - 6*x = 5-11*x
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = - 11 x - 10$$
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
