Answer:
The value of "x" is 5.
Step-by-step explanation:
In order to solve this system of equations, we first have to take the first equation and use it to represent "y" in terms of "x". We do that in the following way...
Now, we need to take the second equation and substitute "y" for the equivalent value in terms of "x". After doing this we will get the following equation, which we can solve to get the value of "x".
Therefore, the value of "x" is 5.
1000000000 because less than this number is 9 digits and more than this numbet is not least
Answer:

Answer:
y is also doubled.
Step-by-step explanation:
Direct proportionality between and means that
or
,
which indicates a linear relationship between and because they are related by a constant.
Therefore, if x is doubled, then the new value of is
The new value of is 2 times the previous; therefore, is doubled as is doubled.
