2*log(0.0)*5*x - 3 = -log(0.0)*5*x
$$x 5 \cdot 2 \log{\left(0.0 \right)} - 3 = x 5 \left(- \log{\left(0.0 \right)}\right)$$
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:
$$\tilde{\infty} x = \tilde{\infty} x + 3$$
This equation has no roots
2*log(0.)*5*(x)-3 = -log(0.)*5*(x)
Expand brackets in the left part
2*log0.*5x-3 = -log(0.)*5*(x)
Expand brackets in the right part
2*log0.*5x-3 = -log0.*5x
Move free summands (without x)
from left part to right part, we given:
$$\tilde{\infty} x = \tilde{\infty} x + 3$$
This equation has no roots
