Answer 1

47-17-2=28
7×4=28
28×4=112
2×7=14
28-112=-84
-84+14=-70
-70-6=-76

Answer 2

Let's solve the expression step by step:

1. Start with the parentheses: (47-17-2) = 28
2. Multiply the result by 4: 28 * 4 = 112
3. Multiply 7 by 4: 7 * 4 = 28
4. Multiply 2 by 7: 2 * 7 = 14
5. Perform the addition and subtraction from left to right: 7 * 4 - 112 + 14 - 6 = 28 - 112 + 14 - 6
6. Continue with the addition and subtraction: 28 - 112 + 14 - 6 = -80 + 14 - 6
7. Finally, complete the last addition and subtraction: -80 + 14 - 6 = -72

So, the value of the expression is -72.
