The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$x = 17$$
We get the answer: x = 17
8*x-(7*x+8) = 9
Expand brackets in the left part
8*x-7*x-8 = 9
Looking for similar summands in the left part:
-8 + x = 9
Move free summands (without x)
from left part to right part, we given:
$$x = 17$$
We get the answer: x = 17
