The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 5 x + 14$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = 14$$
Divide both parts of the equation by -7
We get the answer: x = -2
-2*x+16 = 5*x+30
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 5 x + 14$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = 14$$
Divide both parts of the equation by -7
x = 14 / (-7)
We get the answer: x = -2
