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:
$$- 3 x = x - 11$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = -11$$
Divide both parts of the equation by -4
We get the answer: x = 11/4
2*x-5*x+9 = x-2
Looking for similar summands in the left part:
9 - 3*x = x-2
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = x - 11$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = -11$$
Divide both parts of the equation by -4
x = -11 / (-4)
We get the answer: x = 11/4
