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:
$$- 9 x = 18$$
Divide both parts of the equation by -9
We get the answer: x = -2
2-3*(2+3*x) = 14
Expand brackets in the left part
2-3*2-3*3*x = 14
Looking for similar summands in the left part:
-4 - 9*x = 14
Move free summands (without x)
from left part to right part, we given:
$$- 9 x = 18$$
Divide both parts of the equation by -9
x = 18 / (-9)
We get the answer: x = -2
