When the equation 3x + 2y = 7 is expressed in the form ax+by+c=0, indicate the values of a , b and c *

Answer 1

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

`3x + 2y = 7`

Subtract sides 7

`3x + 2y - 7 = 7 - 7`

`3x + 2y - 7 = 0`

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Compare :

`ax + by + c = 0`

`3x + 2y - 7 = 0`

Thus ;

`a = 3 \: \: , \: \: b = 2 \: \: , \: \: c = - 7`
