Question

which ordered pair is the solution of the equation?
-7x-5y=42
a.) 0,-6
b.) -5,0
c.) 0, -5
d.) -6,0

Answer 1

plug in each values for "x" and "y" in the left hand side and see if you get 42

(a) \(-7(0)-5(-6)=30\ne42\)
(b) \(-7(-5)-5(0)=35\ne42\)
(c) \(-7(0)-5(-5)=25\ne42\)
(a) \(-7(6)-5(0)=42\)

Answer 2

so, which pair satisfies the equation?
