Answer:


\huge\boxed{\sf x = 1}

Explanation:

Given function:

h(x) = 4x + 5

Given that, h(x) = 9.

Put in the above function.

9 = 4x + 5

  • Subtract 5 from both sides.

9 - 5 = 4x

4 = 4x

  • Divide both sides by 4.

1 = x

OR

x = 1

Answer:

  • x = 1

Explanation:

Given :-

Given function,

  • h(x) = 4x + 5

To Find :-

  • Solve for x when h(x) = 9

Solution :-

Substitute value of h(x) as 9 in the above function,


\longrightarrow h(x) = 4x + 5


\longrightarrow 9 = 4x + 5

Subtract 5 from both sides,


\longrightarrow 9 - 5 = 4x - 5


\longrightarrow 4 = 4x

Divide both sides by 4,


\longrightarrow x = 1

Therefore, The value of x is 1.
