Answer:
9.2/5= C
Step-by-step explanation:
7.2- 3C = 2C -2     First, add the 2 on the other side to isolate 2C on one side
+2                   +2
9.2 - 3C = 2C       Next, add 3C to the other side         
+3C   +3C
9.2 = 5C                Finally divide both sides by 5 to find the value of C
9.2/5= 5C/5
9.2/5 = C     by dividing by 5 the 5 cancels out and you're left with the C value
