The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- 56 x = 112$$
Divide both parts of the equation by -56
We get the answer: x = -2
(30-7*x)*8 = 352
Expand brackets in the left part
30*8-7*x*8 = 352
Move free summands (without x)
from left part to right part, we given:
$$- 56 x = 112$$
Divide both parts of the equation by -56
x = 112 / (-56)
We get the answer: x = -2
