3.22 divided by 14 is .23. .23 plus .15 is .38 cents per candy at regular price.
Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).

Step-by-step explanation:
Answer:
y = 3 - 2x
Step-by-step explanation:
The goal is to isolate the y variable
In order to have y by itself (on one side of the equation or equal sign), we must move the other numbers and variables to the other side.
Since 2x is on the same side as y, we have to subtract it from both sides. Subtracting it cancels out the original 2x and leaves the equation to look like this:
y = 3 - 2x
Now the y is isolated
Another example:
-5x + y = 15
To isolate the y, we must cancel out the -5x. Add 5x to both sides. It will cancel out the -5x and bring it to the right side of the equation, resulting in:
y = 15 + 5x
Answer:
Step-by-step explanation:
Solve for the value of :
-Take and subtract it from :
-Subtract both sides and convert to a fraction:
Since both and have the same denominator, then you would subtract the numerator:
-Multiply both sides by , which is the reciprocal of :
-Divide by :
So, therefore, the value of is .
