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:
$$- 3 x = 15$$
Divide both parts of the equation by -3
We get the answer: x = -5
3*x-2*(3*x-2) = 19
Expand brackets in the left part
3*x-2*3*x+2*2 = 19
Looking for similar summands in the left part:
4 - 3*x = 19
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 15$$
Divide both parts of the equation by -3
x = 15 / (-3)
We get the answer: x = -5
