You would need to isolate the "X" variable because it is common in all 3 equations.
Answer:
No it is not a function for sure.
X +5 = -6x - 16
add 16 to both sides
x+21 = -6x
add 6x to both sides
7x+21=0
factor out the seven
7(x+3)=0
if 7 times (x+3) = 0 then (x+3) must equal zero because 7 times 0 is 0
so x+3=0
subtract three from both sides
x= -3
