The solution is (2, -4).

We can solve this with the elimination method. Multiply the first equation by -2 and then add the two equations.

-20x + -12y = 8
20x + 10y = 0      Add the two equations

-2y = 8
y = -4

Now, just input -4 for y into either equation, you will get 2 for x.

What’s the inverse of the function F(x)=2x+1
antoniya [11.8K]

Answer:

Step-by-step explanation:

1.  Replace F(x) with y.

2.  Interchange x and y in  y = 2x + 1:  x = 2y + 1

3.  Solve this result for y:  2y = x - 1, or y = (x - 1)/2

4.  Replace y with:

   -1

F     (x):

   -1             x - 1

F     (x) = -----------

                     2
