F(x)=2x+1 find x if f(x)=16 . Please help with this

Step-by-step explanation:

So we have the function:

And we want to find x such that:

To do so, substitute 16 for f(x):

Subtract 1 from both sides. The right side cancels:

Divide both sides by 2. The left side cancels:

The value of x is 7.5

Step-by-step explanation:

We are given the value of f(x). Insert this value into the original equation:

Solve for x. Subtract 1 from both sides:

Divide both sides by 2 to isolate x:

When f(x) equals 16, x is equal to
