一道英文的数学题,请用英文来回答+为什么这样做

如题所述

1. The formula for Eli's weight after x months is: Weight after x months = 190 - 2x.
2. Eli's initial weight was 190lb, and he planned to lose 2lb every month.
3. After x months, the weight loss would be 2x, so we subtract 2x from the original weight to find the weight after x months.
4. By substituting 8 months for x in the formula Weight(x months) = 190 - 2x, we get 190 - 2 * 8 = 174lb.
5. I believe my explanation is clear enough. I hope it is helpful.
