To see how they are related, let us solve the two equations.
FIRST EQUATION



SECOND EQUATION



Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
There is an 18% chance that out of the 3 students she asks, 3 would be in a band. I hope this helped ^^
Subsitute -4y for x
-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back
x=-4y
x=-4(9)
x=-36
(x,y)
(9,-36)
Answer:
D. Multiplication property of equality
Step-by-step explanation:
5 is multiplied to both sides of the equation, resulting to x = -10
Answer:
-2
Step-by-step explanation:
-3+8x-5=-8
8x = -16
x = -2
