The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$8 x = 5 x + 3$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 3$$
Divide both parts of the equation by 3
We get the answer: x = 1
8*x-15 = -12+5*x
Move free summands (without x)
from left part to right part, we given:
$$8 x = 5 x + 3$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 3$$
Divide both parts of the equation by 3
x = 3 / (3)
We get the answer: x = 1
