I think you should give the phone back to the owner and try getting your money back because this might be a permanent problem , and the phone might have been used by the owner and he might have made an account on the iPhone . If you want to save money by keeping the phone , you can set up a appointment with The Apple Store and they might be able to help you out ! I hope this helps you , good luck .
Answer:
use substitution method
find equation for value of x/y
2x + 2y = 4
2y = 4 - 2x
y = <u>4 - 2x</u> ----> equation 1
2
so..substitute the
equation 1 to -5x+3y=-18
-5x+3( <u>4 - 2x</u><u> </u><u>)</u> = -18
2
-5x + 3(2-x) = -18
6-3x = -18+5x
6+18= 5x+3x
24 = 8x
<u>2</u><u>4</u> = <u>x</u>
8
x= 3. -----> eq.2
sub eq.2 into 1 to find the value of x
y = <u>4-2(3)</u>
2
y = - 1
x=3 ; y= -1
With the zero information you give us, I guess you could make it fx-3f....
