Question

7. The pairs of equations 9x + 3y + 12 = 1 point 0 and 18x + 6y + 26 = 0 have *
Unique solution
Exactly two solutions
Infinitely many solutions
No solution

Answer 1

Answer:

No solution

Step-by-step explanation:

a¹/a²=b¹/b²≠c¹/c²

(=>9/18=3/6=12/26

=>1/2=1/2≠6/13)

Answer 2

Answer:

No solution

Step-by-step explanation:

9x + 3y + 12 = 1

9x + 3y + 11   =  0

18x + 6y + 26 = 0

here

a1/a2=9/18=1/2

b1/b2=3/6=1/2

and c1/c2=11/26

a1/a2=b1/b2 ≠ c1/c2

Thus these equations  have

No solution
