I was wondering how to do this problem.
y=0.7(100+x)
x=0.4(100+y)
I am supposed to use the substitution method to solve it, and this is what I have came up with so far.
y=0.7(100+(0.4(100+y)
y=0.7(100+40+0.4y)
y=0.7(140+0.4y)
y=98+0.28y
-0.28y=98
y=-350
Am I working on this problem in the correct way? If not, could you walk me through it, step by step?
Thanks.
