Step-by-step explanation:
This is easy, all they are asking you to do is plug the numbers for x and y into the equation and see if everything comes out to be zero.
-8[22/7] + 5[127/35] + 7 = ?
-176/7 + 635/35 + 7 = ?
make them all have the same denominator of 35
-880/35 + 635/35 + 245/35
(-880 + 625 + 245)/35 = 0/35 = 0
Yes it equals zero, so the answers they gave you are a valid solution to the equation.
