Only when any equation you find among those numbers can be simplified into one of the four main equations, wich means you only have four different true statements, and lots of equivalences.
Answer:
t= -4
Step-by-step explanation:
t/2-16= -18
first add 16 to both sides
t/2-16+16= -18+16
t/2= -2
now multiply both sides by 2
(t/2)2=-2(2)
t= -4
answer check:
substitute the variable for -4
-4/2-16= -18
-4/2= -2
-2-16= -18
-18= -18
