Answer 2

Answer:

x=-2.5,y=7.5

Step-by-step explanation:

Solution,

3x+y=2.....(1)

x+y=7

or,y=7-x......(2)

Now,by putting the value of y from equation 2 to equation 1,we get

3x+y=2

or,3x+(7-x)=2

or,3x+7-x=2

or,2x+7=2

or,2x=2-7

or,2x=-5

or,x=-5/3

or,x=-2.5

Again,

by putting the value of x in equation 2,we get

x+y=7

or,-2.5+y=7

or,y=7+2.5

or,y=7.5
