The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 170$$
Divide both parts of the equation by 2
We get the answer: x = 85
2*x-20-150 = 0
Looking for similar summands in the left part:
-170 + 2*x = 0
Move free summands (without x)
from left part to right part, we given:
$$2 x = 170$$
Divide both parts of the equation by 2
x = 170 / (2)
We get the answer: x = 85
