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:
$$- 2 x = -14$$
Divide both parts of the equation by -2
We get the answer: x = 7
3*(6+x)-(5*x-3) = 7
Expand brackets in the left part
3*6+3*x-5*x+3 = 7
Looking for similar summands in the left part:
21 - 2*x = 7
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = -14$$
Divide both parts of the equation by -2
x = -14 / (-2)
We get the answer: x = 7
