The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$4 x = - \frac{4979}{10}$$
Divide both parts of the equation by 4
We get the answer: x = -4979/40
x+3*x+500 = (21/10)
Expand brackets in the right part
x+3*x+500 = 21/10
Looking for similar summands in the left part:
500 + 4*x = 21/10
Move free summands (without x)
from left part to right part, we given:
$$4 x = - \frac{4979}{10}$$
Divide both parts of the equation by 4
x = -4979/10 / (4)
We get the answer: x = -4979/40
