The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = - 3 x - 10$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -10$$
Divide both parts of the equation by -1
We get the answer: x = 10
-4*x+7 = 5-(3*x+8)
Expand brackets in the right part
-4*x+7 = 5-3*x-8
Looking for similar summands in the right part:
7 - 4*x = -3 - 3*x
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = - 3 x - 10$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -10$$
Divide both parts of the equation by -1
x = -10 / (-1)
We get the answer: x = 10
