2%2F5x-6=12
Do I multiply both sides by 5
-DW
no, you need to multiply both sides with denominator which is 5x
%282%2F5x%29%2A5x+-+6%2A5x+=+12%2A5x
2+-+30x+=+60x.......add %2B+30x to both sides
2+%2B+30x+-+30x+=+60x+%2B+30x
2+=+90x
or
90x+=+2......divide both sides by 2
45x+=+1 ........divide both sides by 45
45x%2F45+=+1%2F45
x+=+1%2F45
