5x - 3y - z
By hypothesis, x = -2, y = 2 and z = -3.
So you all need to do is replace each letter by its value and do the calculus:
5x - 3y - z = 5*(-2) - 3(2) - (-3)
= -10 - 6 + 3=
=-16 + 3
= -13
So when x = -2, y = 2 and z = -3
5x - 3y - z = -13 (answer d)
Hope this helps! :)
Answer:
Step-by-step explanation:
4690/x = 5/2
cross multiply
(4690)*(2)=5*x
9380=5x
Divide both sides by 5.
x=1876

It would actually be -14 because 5+4-2=7 and if you multiply 7 by -2 you get -14
