Question

[C]. Express the following linear equations in the form ax + by + c = 0

and indicate the value of a , b , and c in each case. (i) -3x + 5y = 6 (ii) 10 = 5x (iii) 6x = 7y (iv) 5y – 3 = 0​

Answer 1

Answer:

Given :2x+3y=9.35

we have to express this in the form of a linear equation of the type,

⇒ax+by+c=0.......(1)

∴2x+3y=9.35

⇒2x+3y−9.35=0.......(2)

comparing (1)&(2) we can say

⇒a=2

b=3

c=−9.35

Hence, solved.

Answer 2

Answer:

(I) -3x + 5y = 6

-3x + 5y - 6 = 0

here; a = -3x , b = 5y , c = -6

(II) 10 = 5x

10 - 5x = 0

10 - 5x + 0 = 0

here; a = 10 , b = -5x , c = 0

(III) 6x = 7y

6x - 7y = 0

6x - 7y + 0 = 0

here; a = 6x , b = -7y , c = 0

(III) 5y - 3 = 0

5y - 3 + 0 = 0

here; a = 5y , b = -3 , c = 0
