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:
$$5 x = 20$$
Divide both parts of the equation by 5
We get the answer: x = 4
(7*x-8)-(2*x-5) = 17
Expand brackets in the left part
7*x-8-2*x+5 = 17
Looking for similar summands in the left part:
-3 + 5*x = 17
Move free summands (without x)
from left part to right part, we given:
$$5 x = 20$$
Divide both parts of the equation by 5
x = 20 / (5)
We get the answer: x = 4
