1. Add 3 to both sides, add 17 and 3 to get 20, divide both sides by -4, divide 20 by-4 to get -5.

x=-5

2. Subtract 9 from Both sides, subtract 9 from 13 to get 4, divide both sides by -2, divide 4 by -2 to get -2.

x=-2

3. Subtract 6 from both sides, subtract 6 from -64 to get -70, divide both sides by 7, divide -70 by 7 to get -10.

X=-10
