The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Divide both parts of the equation by -158/25
We get the answer: x = -19/2
-(158/25)*x = (1501/25)
Expand brackets in the left part
-158/25x = (1501/25)
Expand brackets in the right part
-158/25x = 1501/25
Divide both parts of the equation by -158/25
x = 1501/25 / (-158/25)
We get the answer: x = -19/2
