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