The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 4 x - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = -4$$
Divide both parts of the equation by 3
We get the answer: x = -4/3
8+7*x = 4*x+4
Move free summands (without x)
from left part to right part, we given:
$$7 x = 4 x - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = -4$$
Divide both parts of the equation by 3
x = -4 / (3)
We get the answer: x = -4/3
