112 lbs
thanksssssssss amigossssssss
To find Jill's present weight, let's set up equations based on the given information:
Let x be Jill's present weight.
According to the first statement, her present weight is 14 pounds less than her weight a year ago. We can express this as:
Present weight = Weight a year ago - 14
Also, according to the second statement, her weight at the time was 9/8 of her present weight. We can express this as:
Weight a year ago = (9/8) * Present weight
Now we can substitute the second equation into the first equation:
Present weight = (9/8) * Present weight - 14
To solve this equation, let's simplify it:
(8/8) * Present weight = (9/8) * Present weight - 14
8 * Present weight = 9 * Present weight - 14 * 8
8 * Present weight = 9 * Present weight - 112
Rearranging the equation by moving "9 * Present weight" to the left side:
8 * Present weight - 9 * Present weight = -112
-1 * Present weight = -112
Now divide both sides of the equation by -1:
Present weight = -112 / -1
Present weight = 112
Therefore, Jill's present weight is 112 pounds.
