The solution
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:
$$- 2 x = 32193 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 32193$$
This equation has no roots
7^5-2*x = (49/100)*10^5-2*x
Expand brackets in the right part
7^5-2*x = 49/100*10^5-2*x
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 32193 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 32193$$
This equation has no roots
