because if you think about a fraction as a part of a circle, and each of the denominators standed for one piece of the circle, then there would be way more pieces on the 100 circle and they would be smaller, thus, making 2 of them worth less than 2 of the circle with only 10 pieces.
-5n-8(1+7n)=8 Let's simplify everything. -5n-8-56n=8 Put the variables on one side and the numbers on the other. -5n-56n=8+8 Combine like terms. -61n=16 n=-16/61
