Question

What is the value of x in the equation 2x+3=9?
A) 2
B) 3
C) 4
D) 5

Answer 1

The value of
`x` in the equation
`2x+3=9` is
`3`. So, the correct answer is B)
`3`

Step-by-step explanation:

To solve this type of equation, follow these steps:

1. Isolate the Variable: Start by moving all terms containing the variable (in this case,
`x`) to one side of the equation and the constant terms to the other side. We do this by performing the same operation on both sides of the equation to keep it balanced. For our equation,
`2x+3=9`, we need to get
`x` by itself on one side. So, we subtract
`3` from both sides:

`2x+3-3=9-3`

Simplifying this, we get:

`2x=6`

2. Solve for the Variable: Now, divide both sides of the equation by the coefficient of
`x` (which is 2 in our case) to solve for
`x`:

`x=(6)/(2)=3`
