I think there is a problem with the options :D
<span>When x is 4, </span>
<span>y = 11 (11 =/= 4) </span>
<span>When x is 2, </span>
<span>y = 5 (This is correct) </span>
<span>When x is 4, </span>
<span>y = 11 (11 =/= 3) </span>
<span>When x is 0, </span>
<span>y = -1 (-1 =/= -3)</span>
Answer:
x=12
Step-by-step explanation:

x-5=7
x=5+7
x=12
The first answer to the first question is 27
the second answer to the second question is 2,875 million km
the third answer to the third question is <span>31680000</span>
