The sum of three numbers is -4. the second number decreased by the third is equal to the first. the sum of the first and second numbers is -5. find the numbers

Step-by-step explanation:

X + Y + Z = -4 ( given)

X + Y = -5 (given)

-5 + Z = -4 ( x + Y = -5)

Z = 1

Y - Z = X ( given)

(Y - 1 ) + Y = -5 ( replacing value of X +Y = -5)

2Y = -4

Y = -2

X + Y = -5

X+ (-2) = -5

X = -3

Therefore

X = -3

Y = -2

Z = 1

idk bring the function back   im not smart

step-by-step explanation:

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
