The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$6 x = 5 x - 7$$
Move the summands with the unknown x
from the right part to the left part:
$$x = -7$$
We get the answer: x = -7
6*x-4 = 5*x-11
Move free summands (without x)
from left part to right part, we given:
$$6 x = 5 x - 7$$
Move the summands with the unknown x
from the right part to the left part:
$$x = -7$$
We get the answer: x = -7
