The solution
Detail solution
Given the equation:
$$\frac{x - 6}{x - 9} = 5$$
Multiply the equation sides by the denominator -9 + x
we get:
$$x - 6 = 5 x - 45$$
Move free summands (without x)
from left part to right part, we given:
$$x = 5 x - 39$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = -39$$
Divide both parts of the equation by -4
We get the answer: x = 39/4
$$\frac{x - 6}{x - 9} = 5$$
Multiply the equation sides by the denominator -9 + x
we get:
$$x - 6 = 5 x - 45$$
Move free summands (without x)
from left part to right part, we given:
$$x = 5 x - 39$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = -39$$
Divide both parts of the equation by -4
x = -39 / (-4)
We get the answer: x = 39/4
