The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 12 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$12 x = 12$$
Divide both parts of the equation by 12
We get the answer: x = 1
7*x+13 = -5*x+25
Move free summands (without x)
from left part to right part, we given:
$$7 x = 12 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$12 x = 12$$
Divide both parts of the equation by 12
x = 12 / (12)
We get the answer: x = 1
