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:
$$8 x = 198$$
Divide both parts of the equation by 8
We get the answer: x = 99/4
x+7*x-198 = 0
Looking for similar summands in the left part:
-198 + 8*x = 0
Move free summands (without x)
from left part to right part, we given:
$$8 x = 198$$
Divide both parts of the equation by 8
x = 198 / (8)
We get the answer: x = 99/4
