Answer:
or
Step-by-step explanation:
Substitution means plugging in one variable's value that consists of the opposite variable. Because is already specified, you can plug it into the second equation's
value. After doing that, it looks like this:
Then you would distribute the across the parentheses next to it, like this:
Then, add like terms, like this:
Then divide both side by to isolate
.
Now, you can plug (
) into either equation, but the first one seems simpler so you would pick that. It would look like this:
Solving would look like this:
So the answer is or

The statement, "Julian's sister said he walked 1/5 mile" cannot be agreed because Julian totally walked miles.
<u>Solution:</u>
Given that,
- Julian walked 6/10 of a mile to his friends house
- Another 35/100 mile to the store
- He walked 1/4 of a mile back home
To find total distance walked by Julian we have to add the above stated values. That is,
Factors of 10 =
Factors of 100 =
Factors of 4 =
Therefore, the least common factor of 10, 100 and 4 is 100. With like denominators we can operate on just the numerators,
Which can also be written as .
So, from the above calculation it can be said that Julian walked .
