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:
$$5 x = 33$$
Divide both parts of the equation by 5
We get the answer: x = 33/5
7*x-2*9-2*x = 15
Looking for similar summands in the left part:
-18 + 5*x = 15
Move free summands (without x)
from left part to right part, we given:
$$5 x = 33$$
Divide both parts of the equation by 5
x = 33 / (5)
We get the answer: x = 33/5
