x - (-7/10) = 3 3/5
x + 7/10 = 3 3/5
x +7/10 = 18/5
x + 7/10 = 36/10
x = 29/10
x = 2 9/10

x + 7/10 = 3 3/5
x = 3 3/5 - 7/10
x = 18/5 - 7/10
x = 2 9/10
x = 29/10
x = 2.9
That is answer!

x-(-7/10)=3 3/5
x+7/10=3 3/5
x+7/10=3 6/10
x+7/10=36/10
x+7/10-7/10=36/10-7/10
x=29/10=2 9/10

Same answer as x + 7/10 = 18/5
So get common denominators...
x + 7/10 = 36/10
and subtract 7/10 from each side.
x = 29/10 or x = 2 9/10
