The solution
Detail solution
Given the equation:
$$\frac{2}{11 - x} = 1$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
so we get the equation
$$2 = 11 - x$$
$$2 = 11 - x$$
Move free summands (without x)
from left part to right part, we given:
$$0 = 9 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$x = 9$$
We get the answer: x = 9
$$\frac{2}{11 - x} = 1$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
a1 = 2
b1 = 11 - x
a2 = 1
b2 = 1
so we get the equation
$$2 = 11 - x$$
$$2 = 11 - x$$
