3(8 + -2) - 2(8 - 8(-2))
PEMDAS
3(8−2)−2(8−(8)(−2))
=(3)(6)−2(8−(8)(−2))
=18−2(8−(8)(−2))
=18−2(8−(−16))
=18−(2)(24)
=18−48
=−30                                          FINAL ANSWER

So, 3(x + y) - 2(x - 8y) when x is 8 and y is -2, the answer is -30.

  Solve for 3(x + y) - 2(x - 8y)  --  x = 8 , y = -2
 
     3(x + y) - 2(x - 8y)
 
     3[8 + (-2)] - 2[8 - 8(-2)]
 
     3(8 - 2) - 2(8 + 16)
 
     24 - 6 - 16 - 32
 
     18 - 48
 
     -30        

-----The answer is -30.
