The solution

You have entered [src]
2*x + 1 - 20*x + 15 = 6*x + 4
$$\left(- 20 x + \left(2 x + 1\right)\right) + 15 = 6 x + 4$$
Detail solution
Given the linear equation:
2*x+1-20*x+15 = 6*x+4

Looking for similar summands in the left part:
16 - 18*x = 6*x+4

Move free summands (without x)
from left part to right part, we given:
$$- 18 x = 6 x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-24\right) x = -12$$
Divide both parts of the equation by -24
x = -12 / (-24)

We get the answer: x = 1/2
