Question

2x + 3y = 15
x + y = 6

Answer 1

2x+3y=15 -(1)

x+y=6

x=6-y -(2)

substituting (2) in (1)

2(6-y) +3y=15

12-2y+3y=15

y=3

substituting y=3 in (2),

x=6-y

x=6-3

x=3

Answer 2

Answer:

I know ans

Step-by-step explanation:

2x +3y=15____1

x+y=6-----2

multiplying equation 2 by 2

2x+2y=12 ---------3

now, subtracting Eq 3 from EQ 1

2x+3y=15

2x+2y=12

-------------------------

y=3

substituting y =3 in Eq 2

x+y=6

x+3=6

x=3

solution (x,y) =(3,3)
