You can put this solution on YOUR website!
Remember the direction change when multiplying or dividing by a negative.
1)
7y+-+15+-+4y+%3C=+-18
3y+%3C=+-18+%2B+15
3y+%3C=+-3
highlight_green%28y+%3C=+-1%29
...
2)
19 - 4m > 4m + 11
-4m - 4m > -19 + 11
-8m > -8
highlight_green%28m+%3C+1%29
...
3)
%28-5%2F6%29d+%2B+8+%3E+13
-5d + 48 > 78
-5d > 78 - 48
-5d > 30
highlight_green%28d+%3C+-6%29
...
4)
2%283x%2B1%29+%3C=+4%282x-3%29
6x+%2B+2+%3C=+8x+-+12
6x+-+8x+%3C=+-12+-+2
-2x+%3C=+-14
highlight_green%28x+%3E=+7%29
...
5)
14 - 2%2F5h > 13.9 - 3%2F10h
140 - 4h > 139.0 - 3h
-4h + 3h > 139 - 140
-h > -1
highlight_green%28h+%3C+1%29
