Question

How is this no solution? 9x+8y=15 9x+8y=30. Please show your work.

Answer 1

9x+8y=15
9x+8y=30

There can't be a solution because 9x+8y equal different things in both.

Hope this helps :)

Answer 2

We are given:

 9x + 8y = 15 ; AND:
 
 9x + 8y = 30 ;

  Note that:  15 ≠ 30 ; so there is no solution to this system.
