The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 8 x - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -4$$
Divide both parts of the equation by -1
We get the answer: x = 4
7*x+5 = 8*x+1
Move free summands (without x)
from left part to right part, we given:
$$7 x = 8 x - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -4$$
Divide both parts of the equation by -1
x = -4 / (-1)
We get the answer: x = 4
