Question

solve the equation by elimination method
2x+y=0
3x-y=5​

Answer 1

Answer:

x=1 , y=-2

Step-by-step explanation:

2x+y=0----------(1)

3x-y=5----------(2)

Adding (1) and (2)

3x-y=5

+ 2x+y=0

----------------

5x =5

x=5/5

x=1

Put x=1 in (1)

2x+y=0

2(1)+y=0

2×1+y=0

2+y=0

y=0-2

y=-2
