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 7/10
We get the answer: x = -2
(7/10)*x = -(7/5)
Expand brackets in the left part
7/10x = -(7/5)
Expand brackets in the right part
7/10x = -7/5
Divide both parts of the equation by 7/10
x = -7/5 / (7/10)
We get the answer: x = -2
