The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Divide both parts of the equation by 12/5
We get the answer: x = 2/5
x+x*(7/5) = (24/25)
Expand brackets in the left part
x+x7/5 = (24/25)
Expand brackets in the right part
x+x7/5 = 24/25
Looking for similar summands in the left part:
12*x/5 = 24/25
Divide both parts of the equation by 12/5
x = 24/25 / (12/5)
We get the answer: x = 2/5
