Question

ans plz...................​

Answer 1

Answer:

b) 1

Step-by-step explanation:

values of X and y which satisfy first two eq

eq 2 - eq 1

= 5x+4y-3x -4y = 4-5

2x = -1

X =-1/2

3x +4y = 5

-3/2 +4y =5

4y = 13/2

y = 13/8

first two lines will meet at point (-1/2,13/8)

so for third line also absisa and ordinate should be same

ax+4y = 6

-a/2 = 12-13/2

-a/2 = -1/2

a = 1
