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