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 7/10
We get the answer: x = 3550/7
x-(3/10)*x = 355
Expand brackets in the left part
x-3/10x = 355
Looking for similar summands in the left part:
7*x/10 = 355
Divide both parts of the equation by 7/10
x = 355 / (7/10)
We get the answer: x = 3550/7
