2493 3 2493*(-49) ---- + - -- + ---------- = x 50 10 50*1000
$$\left(\frac{\left(-49\right) 2493}{50 \cdot 1000} - \frac{3}{10}\right) + \frac{2493}{50} = x$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$0 = x - \frac{2355843}{50000}$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = - \frac{2355843}{50000}$$
Divide both parts of the equation by -1
We get the answer: x = 2355843/50000
(2493/50)-((3/10)+(49/1000)*(2493/50)) = x
Expand brackets in the left part
2493/50-3/10+49/10002493/50) = x
Looking for similar summands in the left part:
2355843/50000 = x
Move free summands (without x)
from left part to right part, we given:
$$0 = x - \frac{2355843}{50000}$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = - \frac{2355843}{50000}$$
Divide both parts of the equation by -1
x = -2355843/50000 / (-1)
We get the answer: x = 2355843/50000
