10*(x - 45/4)
22/5 = -------------
135/4
$$\frac{22}{5} = \frac{10 \left(x - \frac{45}{4}\right)}{\frac{135}{4}}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{8 x}{27} - \frac{116}{15}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-8\right) x}{27} = - \frac{116}{15}$$
Divide both parts of the equation by -8/27
We get the answer: x = 261/10
(22/5) = 10*(x-(45/4))/((135/4))
Expand brackets in the left part
22/5 = 10*(x-(45/4))/((135/4))
Expand brackets in the right part
22/5 = 10*x+10*45/4)/135/4)
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{8 x}{27} - \frac{116}{15}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-8\right) x}{27} = - \frac{116}{15}$$
Divide both parts of the equation by -8/27
x = -116/15 / (-8/27)
We get the answer: x = 261/10
