The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$5 x = 7 x + 11$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = 11$$
Divide both parts of the equation by -2
We get the answer: x = -11/2
5*(x-(11/5)) = 7*x
Expand brackets in the left part
5*x+5*11/5) = 7*x
Move free summands (without x)
from left part to right part, we given:
$$5 x = 7 x + 11$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = 11$$
Divide both parts of the equation by -2
x = 11 / (-2)
We get the answer: x = -11/2
