Question

write whether the following pair of linear equation is consistent or not x+y=25; x-y=25​

Answer 1

Answer:

linear equations

Step-by-step explanation:

x_y x-y

Answer 2

Answer :

given

Let a1x + b1y + c1 = x+y =25 and

a2x + b2y + c2 = x-y=25.

so here ,a1 = 1 a2= 1

b1= 1 b2 = -1

c1= -25. c2 = -25

⇒ a1/ a2 = 1

⇒ b1/ b2 = -1

⇒a1/a2 ≠ b1/b2.

Hence the system of equations has unique solution.

Thus the pair of equations are consistent.
