1)
4y-15=-10
4y=-10 +15
4y = 5
y =5/4 = 1.25
2)
3-4d=13
-4d = 13- 3
-4d = 10
d =10/(-4)
d = -2.5
3)
8=9x-7
8-7 = 9x
1 =9x
x = 1/9

I'm sorry to note an error in the previous solution by pushpaharan:
In question #3, you should ADD +7 to each side of the equation:
8=9x-7
8+7 = 9x -7 + 7
15 = 9x
Divide both sides by 9
Reduce the fraction,
