Step-by-step explanation:

Hope you get the correct answer.

Answer 2

1. Subtract  1  from both sides of the equation

2x + 1 = 9

= 2 +  1 −  1 =  9  −  1

2.  Simplify

2  + 1  − 1  = 9 − 1

2 = 9 − 1

3. Subtract the numbers

2x= 9-1

2x= 8

= $\frac{2x}{2}$= $\frac{8}{2}$

= $\frac{8}{2}$

x= 4
