In lewis carroll’s through the looking glass, tweedledum says, "the sum of your weight and twice mine is 361 pounds." tweedledee replies, "the sum of your weight and twice mine is 362 pounds." find both of their weights.

Tweedledum weights 120 pounds and Tweedledee 121 pounds.

Step-by-step explanation:

If we say that is the weight of Tweedledum and is the weight of Tweedledee, according to what they say we can write the equations:

We can solve this easily by substitution for example.

From the first equation we can write:

And substitute in the second equation:

Which means:

Which results in

And we return to the first equation to have:

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
