Step-by-step explanation:
<u>Step 1: Define</u>
-7x + 6 = 27
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 6 on both sides: -7x = 21
- [Division Property of Equality] Divide -7 on both sides: x = -3

Answer:
about 10 without a remainder of 4
Step-by-step explanation:

8 + 25 + 9 + 10 + 11 + 1 is 64.
64/6 is about 10 without a remainder of 4
