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:
$$- 117 x = -1053$$
Divide both parts of the equation by -117
We get the answer: x = 9
9*(143-13*x) = 234
Expand brackets in the left part
9*143-9*13*x = 234
Move free summands (without x)
from left part to right part, we given:
$$- 117 x = -1053$$
Divide both parts of the equation by -117
x = -1053 / (-117)
We get the answer: x = 9
