Let
x------> amount of money Theo has
y------> amount of money Denise has
z------> amount of money Rudy has
we know that
x+y+z=$45-----> equation 1
x=5+y-----> equation 2
y=11+z----> equation 3
substitute equation 2 in equation 1
[5+y]+y+z=45-------> 2y+z=40-----> equation 4
y=11+z----> equation 3
2y+z=40-----> equation 4
resolves the equations system
using a graph tool
see the attached figure
the solution is
y=17
z=6
x=5+y----> x=5+17----> x=22
the answer is<span>
Denise has $17</span>

2) 3(2y-1)+2(3y+1)
Distribute:
=(3)(2y)+(3)(-1)+(2)(3y)+(2)(1)
Combine Like Terms:
=6y+-3+6y+2
=(6y+6y)+(-3+2)
=12y+-1
Answer is: 12y-1
