please send me this question ka answer​

Answer 1

Answer:

add eq 1 & 2

x=1

put x= 1 in eq 2

y=2

Answer 2

Answer:

answer will be(x,y)=(1,2)

Step-by-step explanation:

3x-y=1..so,3x=y+1

so,x=(y+1)/3(3rd equation)

By implanting the quale of x into the equation we get:

2(y+1)/3+y=4

or,2y+2+3y/3=4

or,5y+2=12

or,5y=12-2=10

or,y=10/5

so,y=2

then by implanting the quale of y into the3rd equation,we get:

x=2+1/3

x=3/3

so,x=1

so,(x,y)=(1,2)
