Question

Selve each system of equations using elimination method.
2x+y=0
2x-y=1
​

Answer 1

Answer:

x=3 y=1

Step-by-step explanation:

Given equations are

2x+y=7 ....(1)

and 2x−3y=3 ....(2)

Multiply equation (1) by 3,

6x+3y=21 ....(3)

Add equations (2) and (3) to eliminate y, we get

8x=24

⇒x=3

Substitute this value of x in equation (1),

2(3)+y=7

⇒6+y=7

⇒y=1

Therefore, solution is x=3,y=1.
