To solve for x, isolate it on one side of the equation.

First, you add by 1 from both sides.

$\sf{2x-1+1=9+1}$

Solve.

Add the numbers from left to right.

9+1=10

Rewrite the problem.

$\sf{2x=10}$

Divide by 2 from both sides.

$\sf{(2x)/(2)=(10)/(2)}$

Solve.

Divide these numbers from left to right.

10/2=5

$\rightarrow: \boxed{\sf{x=5}}$

Therefore, the final answer is x=5.

I hope this helps, let me know if you have any questions.
