225*x - 52/7 = ---- + --
4 7
$$225 x - \frac{52}{7} = \frac{17 x}{4} + \frac{61}{7}$$
Detail solution
Given the linear equation:
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$225 x = \frac{17 x}{4} + \frac{113}{7}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{883 x}{4} = \frac{113}{7}$$
Divide both parts of the equation by 883/4
We get the answer: x = 452/6181
3*75*x-52/7 = (17/4)*x+61/7
Expand brackets in the right part
3*75*x-52/7 = 17/4x+61/7
Move free summands (without x)
from left part to right part, we given:
$$225 x = \frac{17 x}{4} + \frac{113}{7}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{883 x}{4} = \frac{113}{7}$$
Divide both parts of the equation by 883/4
x = 113/7 / (883/4)
We get the answer: x = 452/6181
