Question

2x + 9 = 23, find the value of x. *​

Answer 1

Simplifying

2x + -9 = 23

Reorder the terms:

-9 + 2x = 23

Solving

-9 + 2x = 23

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9' to each side of the equation.

-9 + 9 + 2x = 23 + 9

Combine like terms: -9 + 9 = 0

0 + 2x = 23 + 9

2x = 23 + 9

Combine like terms: 23 + 9 = 32

2x = 32

Divide each side by '2'.

x = 16

Simplifying

x = 16

Answer 2

2x + 9 = 23

2x = 23 - 9

2x = 14

x = 14/2

x = 7
