The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 20 x - 18$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-18\right) x = -18$$
Divide both parts of the equation by -18
We get the answer: x = 1
2*x+3 = 3*(3*x-5)+11*x
Expand brackets in the right part
2*x+3 = 3*3*x-3*5+11*x
Looking for similar summands in the right part:
3 + 2*x = -15 + 20*x
Move free summands (without x)
from left part to right part, we given:
$$2 x = 20 x - 18$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-18\right) x = -18$$
Divide both parts of the equation by -18
x = -18 / (-18)
We get the answer: x = 1
