5/7x + 1/2=5/7x+1/2 since x is a variable and 1/2 is a regular number, they can not go together unless a number in multiplication replaces the variable such as x=2, 5/7(2) + 1/2=1 and 13/14 or 27/14.

5/7x + 1/2 = 0
14(5/7x) + 14(1/2) = 0
10x + 7 = 0 - -Clearing the fraction
10x + 7 - 7 = 0 - 7
10x = - 7
10x/10 = - 7/10
x = - 7/10
The answer is x = - 7/10
Insert the x value into the equation
- - - - - - - - - - - - - - - - - - -
Check
5/7(-7/10) + 1/2 = 0
- 35/70 + 1/2 = 0
- 1/2 + 1/2 = 0
0 = 0
- - - - - - - - -
The solution set is { - 7/10 }

5/7x + 1/2
5*2+2*7x /14x
=10+14x /14x

We all know you do not know anything about math because you do not even know what you typed.. Is that an equation? or what?
