Question

Solve the equation
F(x)=2x-4
F(x)=5

Answer 1

x = 4.5

Explanation:

To solve the given equations F(x) = 2x - 4 and F(x) = 5, we need to find the value of x that satisfies both equations.

Since both equations represent the same function, we can set them equal to each other:

`2x - 4 = 5`

Add 4 to both sides of the equation:

`2x - 4 + 4 = 5 + 4`

`2x = 9`

Finally, divide both sides by 2 to isolate x:

`(2x)/(2) = (9)/(2)`

`x = 4.5`

Therefore, the solution to the equation is x = 4.5.

Answer 2

4.5 = x

Explanation:

Solve the equation

F(x)=2x-4

F(x)=5

Setting them equal.

5 = 2x-4

Add 4 to each side.

5+4 = 2x-4+4

9 =2x

Divide each side by 2

9/2 = 2x/2

4.5 = x
