Question

Which of the ordered pairs in the form (x, y) is a solution of this equation?

    (3, –8), (4, 4)
 

     A. Neither is a solution.    B. Both are solutions.    C. The first is a solution, but the second is not.    D. The first is not a solution, but the second is.

Answer 1

you check both of them:
1. 3*3-(-8)/4=9-(-2)=9+2=11 it's true
2. 3*4-4/4=12-1=11 true
so both of them are solutions
