The sum of two numbers is -47 and their difference is one. Find the numbers. Separate with a comma.

let the numbers are x and y

if their sum is 30 and difference is 4

then

x+y=30     1equation

x-y=4          2equation

add both the equations,

2x=34

x=17

then

put the value of x in 1equation,

x+y=30

17+y=30

y=30-17

y=13

then,

first number is 17 and second number is 13

Other explanation: X+y=30 and x- y = 4 ( let x be considered the greater no)

By elimination method

X+y=30-1eq

X-y=4-2eq

2x=34(by adding eq 1 and 2)

X=17

Thus the no's are 17 and y=30-17=13

-23, -24

Step-by-step explanation:

Adding negative numbers gets you another negative number. Therefore the numbers must be -23 and -24.

47 - 90 = 43

43 - 180 = x

x = 137
