Could someone tell me what the answers are to these math problems and how u solved it

a) 2/a +2/b -2/ab
b)5 + x/y - y/x
c)1/3x+2+ + 1/x+1 + 1
d)7/x+1 + x-1


it looks weird i know but / means divided by and i don't know how to write divided by with this -- so yea...

thnx :P

appears to have no solving....just rewriting
a) [ 2a + 2 b - 2 ] / [ ab]
b) [ 5xy + x ² - y ² ] / [ xy ]
c) am guessing you don't type mathematics well...
{ [ x + 1] + [ 3x + 2] + [ x + 1 ][ 3 x + 2] } / { [ 3x + 2][x + 1 ] }
d) { 7 + [ x + 1 ] [ x - 1 ] } / { x + 1 }
