equations
consistent or inconsttent .
5x - 4y+8=0
7x+6y+8_0​

Answer 1

Answer:

Hey-o!

The pair of equations are consistent.

Step-by-step explanation:

Let a1x+b1y+c1=5x-4y+8 and a2x+b2y+c2=7x+6y+8

Therefore a1 =5,b1= -4,c1=8 and a2=7,b2=6,c2=8.

Now, a1/a2=5/7 , b1/b2= -4/6

Therefore, a1/a2 ≠ b1/b2(as 5/7≠ -4/6)

As we have a unique solution,

the above pair of equations are consistent.
