Answer 2

Answer:

2. 3x + 4y = 11

2x + 3y = 8

(-)

=> x+y=3

so, x= 3-y

substituting this on eqn 1

3x + 4y = 11

3(3-y) + 4y = 11

9y -3y + 4y = 11

6y + 4y = 11

10y = 11

y = 11/10

substituting y on eqn 2,

2x + 3y = 8

2x + 3(11/10) = 8

2x + 33/10 = 8

2x = 8×10/33

x = 8×10/33×2

x = 40/33
