Question

x+2y= -1......E-1
2x-3y=12.....E-2
By elimination method

Answer 1

Answer:

answer us in the attachmen :x=-5

and y=2

Answer 2

Multiply eq-(1) by 2

2x+4y+2=0-(3)

Add Eq-(3)&(2)

Refer Attachment for addition

we get, y= 2-(4)

• •Using eq-(4) in eq-(1) or eq(2)•

I prefer using in eq-(1)*

x+2×2=-1

x+2×2=-1x=-1-4

x+2×2=-1x=-1-4x=-5

x=-5

x=-5and

x=-5andy=2

hope it helps
