Question

The solution of 3x + 5 = x + 9 is​

Answer 1

3x-x = 9-5

2x=4

x=4/2

x=2

The answer is 2

Answer 2

Given,

The given equation :

3x+5 = x+9

To find,

Solving the given equation and finding the value of 'x'.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Here, we will use the normal algebraic methods to solve the given equation and to find the value of 'x'. The final value of 'x' should satisfy the given equation.

So,

3x+5 = x+9

3x-x = 9-5

2x = 4

x = 4/2

x = 2

(This cannot be further simplified. And, this value of 'x' satisfies the given equation. So, we will consider this as our final result.)

Hence, the value of 'x' will be 2
