$$\frac{12 \left(x + \frac{49}{50}\right)}{5} = \frac{102}{25}$$
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:
$$\frac{12 x}{5} = \frac{216}{125}$$
Divide both parts of the equation by 12/5
We get the answer: x = 18/25
(12/5)*(x+(49/50)) = (102/25)
Expand brackets in the left part
12/5x+49/50) = (102/25)
Expand brackets in the right part
12/5x+49/50) = 102/25
Move free summands (without x)
from left part to right part, we given:
$$\frac{12 x}{5} = \frac{216}{125}$$
Divide both parts of the equation by 12/5
x = 216/125 / (12/5)
We get the answer: x = 18/25
