Answer:

1. -3    

2. 7      

3. -2        

4. 3

Step-by-step explanation:

1.      idk

2.     3.2 move 3b over to get 3.2-3b-4.7=-3.3 move 4.7 over to get

3.2b-3b=4.7-3.3 now 3.2b-3b=.2b and 4.7-3.3=1.4  .2b/.2=b   1.4/.2=7 so b=7

3.     4.6y-y+4=y-1.2 now switch the 4 and the y to read 4.6y-2y=-4-1.2

2.6y=-5.2 divide both sides by 2.6 to get y=-2

4.      7.5c-2.5c+8=-7 move 8 to other side to get 7.5c-2.5c=-8-7

5c=-15 divide both sides by 5 getting c=3
