Express the following linear equations in the form ax + by + c = 0

Solution:

(i) We are given

- 2x + 3y = 12

- 2x + 3y - 12 = 0

Comparing the given equation with ax + by + c = O

We get, a = - 2; b = 3; c = -12

(ii) We are given

x - y/2 - 5= 0

Comparing the given equation with ax + by + c = 0,

We get, a = 1; b = – 1/2, c = – 5

(iii) We are given

2x + 3y = 9.35

2x + 3y - 9.35 =0

Comparing the given equation with ax + by + c = 0

We get, a = 2; b = 3; c = - 9.35

(iv) We are given

3x = - 7y

3x + 7y = 0

Comparing the given equation with ax+ by + c = 0,

We get, a = 3; b = 7; c = 0

(v) We are given

2x + 3 = 0

Comparing the given equation with ax + by + c = 0,

We get, a = 2; b = 0; c = 3

(vi) We are given

y - 5 = 0

Comparing the given equation with ax + by + c = 0,

We get, a = 0; b = 1; c = – 5

(vii) We are given

4 = 3x

3x - 4 = 0

Comparing the given equation with ax + by + c = 0,

We get, a = 3; b = 0; c = - 4

(viii) We are given

y = x/2

Taking L.C.M ⟹ x - 2y = 0

Comparing the given equation with ax + by + c = 0,

We get, a = 1; b = – 2; c = 0
