Question

The sum of three numbers is 2. the first number minus the second plus the third is negative 2−2. the first minus the third is 22 more than the second. find the numbers\

Answer 1

x is the 1st number, y is the 2nd number, z is the 3d number.

x+y+z = 2

x - y + z= -2

x - z = y +22 -----> x-y-z=22

x+y+z = 2

x - y + z= -2

2x + 2z =0

x + z = 0

x = -z

x - y + z= -2 and x = -z

-z - y + z = -2, y =2

x-y-z=22 and x = -z, and y = 2 -----> x -2 +x = 22 --->2x = 24 ----> x = 12

x= -z -----> z = - 12
