Answer:
x=16
Step-by-step explanation:
since y=7 when x=8 and your trying to find what x is when y=14. Your really just taking the y value which is 7 then multiplying it by 2 which is 14. then since you multiplied the first y value by 2 you then just multiply the 8 by 2 and that is 16.
Answer:

Step-by-step explanation:
To answer this question you need to get the same denominator (bottom number of a fraction ) on both values
Because 7 is a factor of 35, you can multiply the whole fraction by 5, (so that the first fraction has a denominator of 35 which is the same as the other value)
×5
then you add them up but remember if the denominator is the same you do <u>not </u> add them.
