Homework Help: Algebra

Posted by mike on Friday, December 25, 2009 at 12:19pm.

define the following new variables

X to A =W
X to B =X
Y to A =Y
Y to B =Z

w+x=32
y+z=8
w+y=22
x+z=18

You helped me solve for y Ijust added w+y=32

220w+300(32-w)+400(22-w)+180(8-y)=9280

,

w+y=22

The answer I got was y=32 I solved for x and got x=42 I don't know if this is right. I am trying to solve for w and z but keep coming up with fractions. I am using the substitution method to calculate. Thank you Can you help me understand.
