The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{7} = \frac{3 x}{5} - 11$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-11\right) x}{35} = -11$$
Divide both parts of the equation by -11/35
We get the answer: x = 35
2/7*x+4 = 3/5*x-7
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{7} = \frac{3 x}{5} - 11$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-11\right) x}{35} = -11$$
Divide both parts of the equation by -11/35
x = -11 / (-11/35)
We get the answer: x = 35
