just reposting :):) i still don't really get it.

"Tweedledum says: the sum of your weight and twice mine is 361 lbs.
Tweedledee says: contrariwise, the sum of your weight and twice mine is 362 lbs
if both are right how much do they weigh together?"

i got this part, but the next part i can't figure out:

"find tweedledum's and tweedledee's weights in problem 1."

please help,
melanii

Mel, I told you already-- 120 and 121. How much they weigh together would be one number-- 141, I guess. I actually don't know how you would figure that part out, but the second part is correct.

erg i still don't really get it. oh well

Sorry... I tried my best to explain it. Did you look back at my other explanation to the first time you asked it? That might help. It's basically the way our teacher showed us.

yeah.........................

To find Tweedledum's and Tweedledee's weights, we need to solve the system of equations based on the information given by them:

Let's assume Tweedledum's weight is represented by 'D' and Tweedledee's weight is represented by 'E'.

According to Tweedledum: D + 2E = 361 lbs ---(Equation 1)

According to Tweedledee: D + 2E = 362 lbs ---(Equation 2)

To solve this system of equations, we can use the method of substitution:

Step 1: Simplify Equation 1:
D + 2E = 361 lbs

Step 2: Simplify Equation 2:
D + 2E = 362 lbs

Step 3: Subtract Equation 1 from Equation 2:
(D + 2E) - (D + 2E) = 362 - 361
0 = 1

Step 4: Analyzing the result:
Since we get an inconsistent equation where 0 equals 1, it means there is no solution that satisfies both Tweedledum and Tweedledee's statements simultaneously. In other words, their statements contradict each other, and we cannot determine their exact weights.

Therefore, we cannot find Tweedledum's and Tweedledee's weights in this case.
