Question:

Write each of the following as an equation in two variables:

(i) 2x = – 3

(ii) y = 3 

(iii) 5x = 7/ 2

(iv) y = 3/2x

Solution:

(i) We are given,

2x = - 3

Now, in two variable forms the given equation will be

2x + 0y + 3 = 0

(ii) We are given,

y = 3

Now, in two variable forms the given equation will be

0 x + y - 3 = 0

(iii) We are given,

5x = – 7/2

Now, in two variable forms the given equation will be

5x + 0y + 7/2 = 0

10x + 0y - 7 = 0

(iv) We are given,

y =  32x  (Taking L.C.M on both sides)

Now, in two variable forms the given equation will be

3x - 2y + 0 = 0
