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:
$$23 x = -2$$
Divide both parts of the equation by 23
We get the answer: x = -2/23
13*x+10*x+2 = 0
Looking for similar summands in the left part:
2 + 23*x = 0
Move free summands (without x)
from left part to right part, we given:
$$23 x = -2$$
Divide both parts of the equation by 23
x = -2 / (23)
We get the answer: x = -2/23
