The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$14 x = 20 x + 34$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-6\right) x = 34$$
Divide both parts of the equation by -6
We get the answer: x = -17/3
14*x-25 = 20*x+9
Move free summands (without x)
from left part to right part, we given:
$$14 x = 20 x + 34$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-6\right) x = 34$$
Divide both parts of the equation by -6
x = 34 / (-6)
We get the answer: x = -17/3
