w+s+d = 3600
w = s+500, so s = w-500
s = 2d, so d = s/2 = w/2 - 250
Now just solve for w.
w + (w-500) + (w/2 - 250) = 3600
5w/2 = 4350
w = 2/5 * 4350 = 1740
check: 1740 + 1240 + 620 = 3600
w = s+500, so s = w-500
s = 2d, so d = s/2 = w/2 - 250
Now just solve for w.
w + (w-500) + (w/2 - 250) = 3600
5w/2 = 4350
w = 2/5 * 4350 = 1740
check: 1740 + 1240 + 620 = 3600
