Answer:
The answer will be listed below.
Step-by-step explanation:
No Solution: -2z+2+4z=16/5+2z-6/5; 5r+2=6r+3-r
One Solution: 3/2x+2.3-1/2x=4.3+x; 2x+2/3=2x+4/5-4x; 32p-2.5+2.1p=5p-7/2
Infinite Solution: 17/4+4.2y-9/4=2.2y+6+2y-4
Note: Remember that infinite solution is like 1=1 or 5x+2=5x+2. No solution is where it's like 0=1. 1 solution is where it's like x=2.
