Solve the equation and check the solution:
4(t+7)(t+6)=10
the solution t is:

 4 ( t + 7 )  ( t + 6 ) = 10
 4 * t  4 * 7  t + 6 = 10
 4 t  28  t  6 = 10
 5 t  34 = 10 Add 34 to both sides
 5 t  34 + 34 = 10 + 34
 5 t = 44 divide both sides by  5
t =  44 / 5 =  8.8
 4 ( t + 7 )  ( t + 6 ) = 10
 4 (  8.8 + 7 )  (  8.8 + 6 ) = 10
 4 * (  1.8 )  (  2.8 ) = 10
7.2 + 2.8 = 10
10 = 10
