Question

Solve for xF(x)=2x+10

Answer 1

So:

f(x) = 2x + 10

To solve for x, we are going to subtract 10 on both sides of the equation:

f(x) - 10 = 2x + 10 - 10

f(x) - 10 = 2x

Then, dividing by 2, we get:

`\begin{gathered} (f(x)-10)/(2)=(2x)/(2) \\ (1)/(2)f(x)-5=x \end{gathered}`

Answer:

`x=(1)/(2)f(x)-5`
