The point of this equation is to figure out the value of the y variable. to do this, you'll need to get the y variable by itself on one side of the equation. 

so first you would add 6.9 to 3.18. 
the equation would now look like this: 
4.8y=10.08 


you would then divide 4.8 by 10.08. this is the last step to getting the y varible by itself on one side of the equation and ultimately the value of y! 
the equation now looks like this: 
y=2.1 

y=2.1 is you answer!
Good luck!

4.8y - 6.9 = 3.18 
4.8y= 3.18 + 6.9 (I added 6.9 to both sides)
4.8 y = 10.08 (I added 3.18 by 6.9)
y = 2.1 (I divided 4.8)

Hope this helps!!

Which of the following is the inverse of f(x)=3-x/5?​
pshichka [43]

Answer:

-5x+3 OR 5x-3

Step-by-step explanation:

You find the inverse by replacing the x with the y, and solving for y. Doing this actually gives you -5x+3 but in this case,  the closest answer would be 5x-3.

UPDATE: -5x + 3 can be written as 3 - 5x lol

X+y=c<br> x−y=a<br><br> solve for x and y
MrRissso [65]

Answer:

x = (c+a)/2

y = (c-a)/2

Step-by-step explanation:

Add the two equations and you get ...

(x +y) +(x -y) = (c) +(a)

2x = c+a

x = (c+a)/2

--

Subtract the second equation from the first and you get ...

(x +y) -(x -y) = (c) -(a)

2y = c-a

y = (c-a)/2

Comment on this problem

This is what I call a "sum and difference" problem. The solution shown here is (obviously) the generic solution to such a problem. Remembering this can get you quickly to the answer any time you're given the sum of two unknowns and their difference.
