w- walking j- jogging

2w + .5j= 6.25 --> 3(2w+.5j)= 3(6.25)

3w + 1j= 10.25 --> -2(3w+1j)= -2(10.25

6w + 1.5j= 18.75

-6w - 2j= -20.50

-----------------

-.5j=-1.75

j=.3

2w + .5(.3)= 6.25

2w + 15= 6.25

2w= 6.10 w= 3.05

check:

2(3.05) + .5(.3)= 6.25 (correct)

3(3.05) + 1(.3)= 9.45(wrong!!) it should be 10.25.

Where am i going wrong?

**Reiny**, Thursday, October 15, 2009 at 11:58pmok up to

-.5j=-1.75

then

j = 3.5 (you had j= .3)

back in 3w + j = 10.25

3w + 3.5 = 10.25

w = 2.25
