Question

solve the pair of linear equation:X+3y=6,2x-3y=12​

Answer 1

Step-by-step explanation:

x+3y =6 ......1

2x -3y=12 .......2

= 3x=18

x = 6

put the value of x in eq 1

6+3y =6

3y =0

y = 3

so x= 6

y = 3

Answer 2

Step-by-step explanation:

x+3y=6

-2x-3y=-12

-x+0=-6

x=6

now putting the value of x in x+3y=6

6+3y=6

3y=6-6

3y=0

y=0

x=6 and y=0
