It is true. Guptas did figure out the earth was round by observing lunar eclipses.
11% = 16.5
1% = 16.5 / 11
= 1.5
100% = 1.5 * 100
= 150. His weight two years ago was 150 pounds.
To make this easier to read, I'll be substituting 1/2 for .5; they mean the same thing, but it's less confusing to type it in its decimal form.
7x + .5 + 6x - 9.5
Combine like terms (x's can be added together, and so can reg. numbers)
(7x + 6x) + (.5 - 9.5)
13x - 9
