The equation is 44 = t \"\" 72.

\

According to additon property of equality: If a = b, then a + c = b + c.

\

44 + 72 = t \"\" 72 + 72          (Add 72 to each side)

\

  44 + 72 = t                            (Additive inverse property: \"\"72 + 72 = 0)

\

  t = 116                                  (Add: 44 + 72 = 116)

\

\"\"

\

  Check:

\

  To check the solution, substitute t = 116 in original equation.  

\

  44 = t \"\" 72\"\"44 = 116 \"\" 72        

\

  44 = 44                                 (Subtract: 116\"\"72 = 44 )

\

  The equation is true. 

\

\"\"

\

The value of t = 116.
