The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 27 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- 5 x = 27$$
Divide both parts of the equation by -5
We get the answer: x = -27/5
-7*x+3 = 30-2*x
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 27 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- 5 x = 27$$
Divide both parts of the equation by -5
x = 27 / (-5)
We get the answer: x = -27/5
