5x- 6    Just sub in 7, -14  and 0       and we have

 

5(7)-6  = 35 - 6 = 29

5(-14) - 6  =  -70 - 6  = -76

5(0) - 6  = 0 - 6 = 6  

 

There's nothing to do for -11 - 4      this just equals -15

 

[ 4x + 7 ] / 7      again sub in   7, -14  and 0

[ 4(7) + 7] / 7  =  [35/7]  =  5

[4(-14) + 7 ] /7  = [ -49]/7  = -7

[4(0) + 7 ] / 7  =   7 / 7   =   1

 

The last one is

[ 4x ] / 7  +  7         sub in  7, -14 and 0

 

Can you finish it ????

 

cool cool cool
