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:
$$- 3 x = 4 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 4$$
Divide both parts of the equation by -1
We get the answer: x = -4
6-3*(x+1) = 7-2*x
Expand brackets in the left part
6-3*x-3*1 = 7-2*x
Looking for similar summands in the left part:
3 - 3*x = 7-2*x
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 4 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 4$$
Divide both parts of the equation by -1
x = 4 / (-1)
We get the answer: x = -4
