The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Divide both parts of the equation by 4/5
We get the answer: x = 1250
x-(1/5)*x = 1000
Expand brackets in the left part
x-1/5x = 1000
Looking for similar summands in the left part:
4*x/5 = 1000
Divide both parts of the equation by 4/5
x = 1000 / (4/5)
We get the answer: x = 1250
