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:
$$8 x = 16$$
Divide both parts of the equation by 8
We get the answer: x = 2
7*x+x+3 = 19
Looking for similar summands in the left part:
3 + 8*x = 19
Move free summands (without x)
from left part to right part, we given:
$$8 x = 16$$
Divide both parts of the equation by 8
x = 16 / (8)
We get the answer: x = 2
