Question 85383

Let x=length of arm on 96kg side
And y=length of arm on 48kg side

Then 96x=48y or
2x=y---------------------------------eq1

Now we are told that x+y=24------------------------------eq2

From eq1, substitute y=2x into eq2 and we have:

x+2x=24  collect like terms

3x=24
x=8m-------------------------length of arm on 96 kg side

substitute x=8 into eq1 and we get

2*8=y or
y=16m--------------------------length of arm on 48kg side


Hope this helps---ptaylor
