Answer:
see below
Explanation:
1. x-9=-17-simplifies to a single solution-one solution
2.x+4=4+x-same thing on each side-infinite solutions
3. 0.4x=0.4x+2-same variable coefficient plus a number-no solutions
4. 5x=5x-3-same as above-no solutions
5. 5x=2-variable on one side, constant on another-one solution
6. x-5=x-5-same thing on each side-infinite solutions
7.3x=3x-same thing as above-infinite solutions
8.8x-10=8x-same coefficient for each variable plus a constant-no solutions
