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:
$$- 3 x = -10$$
Divide both parts of the equation by -3
We get the answer: x = 10/3
7-3*(x-1) = 0
Expand brackets in the left part
7-3*x+3*1 = 0
Looking for similar summands in the left part:
10 - 3*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = -10$$
Divide both parts of the equation by -3
x = -10 / (-3)
We get the answer: x = 10/3
