Answer 2

Answer:

=> -4

Step-by-step explanation:

Given expression:-

3x - 1

And the value of x is -1,

We have to find the value of the above expression,

Now, put the value of x as -1 in the given expression,

As we have,

$=> 3x - 1$

$=> 3 ( -1 ) - 1$

$=> ( -3 ) - 1$

$=> -4$

Hence, the value of the expression 3x - 1 is -4.
