Answer both questions and show all your work. ! : ) 1) there are 1000 rabbits and chickens on a farm and together they have 3150 legs. how many rabbits and how many chickens are there on the farm? 2) mike has 4 times as many stamps as andrew. if mike gives andrew 8 stamps, he will have twice as many stamps as andrew. how many stamps does each boy have?

(1) let "r" denote number of rabbits, "c"  number of chickens

Set up the equations:

There are 575 rabbits and 425 chickens

(2) m - number of Mike's stamps, a - number of Andrew's stamps.

Set up equations:

 Mike has 48 stamps. Andrew has 12 stamps.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

first one because it can't have a fraction in it
