Question

If xy+z=y what is x in terms of y and z?
a) y+z/y
b) y-z/z
c) y-z/y
d) 1-z
e) z-y/y

Answer 1

to isolate x first subtract z from both sides, what do u get ?

Answer 2

xy=y-z i think

Answer 3

yup,
now since y is 'multiplied' by x on left, to get only x, u divide both sides by y, what u get?

Answer 4

x=-z

Answer 5

nopes, u divide it like this :
\(\huge\frac{xy}{y}=\frac{y-z}{y}\)
to get \(\huge x=\frac{y-z}{y}\)
got it ?

Answer 6

yes than you

Answer 7

welcome :)
