Answer :

The value of [x] for which the equation (3x − 1 = 9x + 2) is true will be -1/2.

What is Expression?

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.

Given is the equation as -

3x − 1 = 9x + 2

We have -

3x − 1 = 9x + 2

Solving, we get -

3x - 9x = 2 + 1

- 6x = 3

x = -3/6

x = -1/2

Therefore, the value of [x] for which the equation (3x − 1 = 9x + 2) is true will be -1/2.
