Question

2× - y =2
6× - 3y =12​

Answer 1

(i)2×-y=2

-y=2÷2

-y=0

(ii) 6×-3y=12

-3y=12÷2

-3y=6

y=6÷(-3)

y=-2

Answer 2

Consider the given equation.

x+3y=6             …….. (1)

2x−3y=12           ……… (2)

On adding both equation (1) and (2), we get

3x=18

x=6  

Now, put the value of x in equation (1), we get

6+3y=6

3y=6−6

3y=0

y=0

Hence, the value of x is 6 and y is 0.
