Question

jhonyy9 · Answer

let Savanna note x
Ryan note y
Sebastian note z

x=24+y
z=5y
x=z    this substitute in place of x in the first equation and will get one system of equations 

z=24+y
z=5y  this just you need substitute in place of z in the first equation and will get the value of y - using this value of y you can calculi easy the value of z and in this way because z=x you have solved this system for x,y and z 

hope these will help you sure
