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
y=1/2

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
