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:
$$3 x = 30$$
Divide both parts of the equation by 3
We get the answer: x = 10
8*x-5*x+4 = 34
Looking for similar summands in the left part:
4 + 3*x = 34
Move free summands (without x)
from left part to right part, we given:
$$3 x = 30$$
Divide both parts of the equation by 3
x = 30 / (3)
We get the answer: x = 10
