Solution

Given:
• 3x/2 = y ……... (1)
• 2 – 3y = y + 2 ……… (2)

To find:
• The value of x

Approach and Working:
• From equation (2), we get, 4y = 0
o Implies, y = 0
• Substituting y = 0 in equation (1), we get, x = 0

Hence, the correct answer is Option C

2 - 3y = y + 2

4y = 0

y = 0.

Given

$$\frac{3x}{2}$$= y

$$\frac{3x}{2}$$= 0

3x = 0

x = 0.

$$2 - 3y = y + 2$$

Or, $$4y = 0$$

So, $$y = 0$$

Thus, $$\frac{3x}{2} = 0$$

Hence, x = 0 ; Answer must be (C)

Simplifying the second equation we have:

2 = 4y + 2

0 = 4y

0 = y

Thus,

3x/2 = 0

3x = 0

x = 0
