Answer:a=3b=-7and c=21Step-by-step explanation:3x=7y-21

Subtracting 7y from both sides

3x-7y=7y-7y-21

3x-7y=-21

Now adding 21 both sides

3x-7y+21=-21+21

## 3x-7y+21=0

Comparing with

ax+by+c=0a=3b=-7and c=21Answer:a=3 ,b=-7 ,c=21

Step-by-step explanation:3x-7y+21=0

ax+by+c=0

where a=3 ,b=-7 ,c=21
