The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$6 x = 13 - 7 x$$
Move the summands with the unknown x
from the right part to the left part:
$$13 x = 13$$
Divide both parts of the equation by 13
We get the answer: x = 1
6*x+12 = -7*x+25
Move free summands (without x)
from left part to right part, we given:
$$6 x = 13 - 7 x$$
Move the summands with the unknown x
from the right part to the left part:
$$13 x = 13$$
Divide both parts of the equation by 13
x = 13 / (13)
We get the answer: x = 1
