Question

Solve for x:
2x - 1 = 9

Answer 1

Explanation:

2x -1 = 9

2x = 1+9

2x=10

x= 10/2

x = 5

Answer 2

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

2x-1=9

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.
