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:
$$3 x = 7$$
Divide both parts of the equation by 3
We get the answer: x = 7/3
6*x-3*x+1 = 8
Looking for similar summands in the left part:
1 + 3*x = 8
Move free summands (without x)
from left part to right part, we given:
$$3 x = 7$$
Divide both parts of the equation by 3
x = 7 / (3)
We get the answer: x = 7/3
