The transitive property of equality states that
if a = b, then ac = bo
if a = b and b = c, then a = 0
if a = b and c = c, then a + b = b +0
if a = b, then b = a.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

y=x+9

?
