Question

3x-y=2 ; 2x+y=8 plz give answer ​

Answer 1

Answer:

x=10

y=28

Step-by-step explanation:

3x-y=2

2x+y=8

x=10

substitute x=10 in 1

3(10)-y=2

30-y=2

-y=2-30

-y= -28

y=28

Answer 2

3x-y=2

=y=3x-2 .....(i)

Again,

2x+y=8

By substituting the value of y from (i),

We have,

2x+3x-2=8

5x=10

x=2

Therefore,

x=2

y=3x-2=6-2=4
