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
