Answer:x=2 and y=1/2

Step-by-step explanation:

X+2y=-1 ....... eq1

2x-3y=12....... eq2

In eq1 multiply we 2

2x+4y=-2....eq3

eq3 - eq2

7x=-14

x=-2

Answer:

x = 3 and y = -2

Step-by-step explanation:

x + 2y = - 1

x = -1 - 2y  ........(1)

2x - 3y = 12

x = 12 + 3y   ........(2)

         2

Equate both 1 and 2

-1 - 2y =  12 + 3y

                  2

-2 - 4y = 12 + 3y

7y = -14

y = -2   ..........(3)

Place 3 in 1 or 2

x = -1 - 2y

x = -1 - 2(-2)

x = -1 + 4

x = 3
