Question

2. Solve the following system by any method.
8x + 9y = –5
–8x – 9y = 5

Answer 1

Infinitely many solutions.

Step-by-step explanation

The given system t;

8x + 9y = –5

–8x – 9y = 5

We use the elimination method:

Let us add the two equations to obtain:

-8x+8x+9y-9y=-5+5

This simplifies to:

0=0

This implies that, the system has infinitely many solutions because the two lines coincide.
