express the equation 3x=7y-21 in the form of ax+by+c=0 and wrote the values of a,b, and c About the author Ella

Answer: a=3 b=-7 and c=21 Step-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=0 a=3 b=-7 and c=21 Reply

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
