The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 19$$
Divide both parts of the equation by -3
We get the answer: x = -19/3
x+5*2-4*x = 29
Looking for similar summands in the left part:
10 - 3*x = 29
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 19$$
Divide both parts of the equation by -3
x = 19 / (-3)
We get the answer: x = -19/3
