Question

If h(x) =5 for the function h(x) =2x+1 what is the value of x

Answer 1

h (x) = 5

h (x) = 2x + 1

h (x) = 2 x 2 + 1 = 5

x = 2

Answer 2

x = 2

Explanation:

Its given that h(x) = 2x + 1

But its also given that h(x) = 5

`=> h(x) = 2x + 1 = 5`

`=> 2x + 1 = 5`

Solve the equation.

• Substract 1 from both the sides.

`=> 2x + 1 - 1 = 5 - 1`

`=> 2x = 4`

• Divide both the sides by 2.

`=> (2x)/(2) = (4)/(2)`

`=> x = 2`
