Question

Find the solution of given linear pair
of equations: x - y = -1 and 3x + 2y =
12​

Answer 1

Step-by-step explanation:

x-y+1 =0 ---A

3x+2y-12 =0 ---B

2A+B =

2x-2y+2 =0

3x+2y-12=0

_________

5x -10 =0

__________

x=10/5 =2

3A-B =

3x-3y+3=0

3x+2y-12=0

_-____+____

-y+15=0

___________

y=15

x = 2, y= 15
