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
