The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = - 4 x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$x = -5$$
We get the answer: x = -5
12-3*x = -4*x+7
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = - 4 x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$x = -5$$
We get the answer: x = -5
