First, you need to isolate the x in the first equation.
-x + 5y = 1
Subtract 5y from both sides, leaving you with the following equation:
-x = 1-5y
Because you are trying to solve for positive x and not negative x, you need to make x positive. Therefore you divide both sides by -1. In Algebra, when 1 is the coefficient of the variable, it is not shown, but it is still there. The new equation will be the following: x = 5y-1
Now you just need to substitute the x within the second equation for the x equation we just solved for.
Therefore, the right answer will be 2(5y-1)+4y= -4. Now, all you have to do is choose the answer that states exactly that, which is the first choice.
61.5 = 3/4 of the way
So:
(61.5)/3 = 20.5 <---- This is 1/4 of the entire journey, and because he has gone 3/4 of the journey already, this is how long it will take him to get home.

Given:
The set of ordered pairs in the options.
To find:
The set of ordered pairs which does not represent a function.
Solution:
A set of ordered pairs represents a function if their exist a unique y-value for each x-value.
In option 3, the given set of ordered pair is:
{(−3,−3),(4,1),(−3,3),(2,2)}
Here, we have to y-values -3 and 3 for x=-3. It means the y-value is not unique for x=-3. So, this set of ordered pairs is not a function.
In option 1, 2 and 4, all the x-coordinates are different. It means their exist a unique y-value for each x-value. So, the set of ordered pairs in options 1, 2 and 4 represent a function.
Therefore, the correct opting is 3.

Answer:
w = 12
Step-by-step explanation:
4w + 9 = 57
4w = 57 - 9
4w = 48
w = 48/4
w = 12
I hope it helps u dear
