Evaluate if x = -3
3x - 4
Help ???
3x - 4
(3*-3) - 4
-9 - 4 = -13
Thanks !!
You're very welcome.
To evaluate the expression 3x - 4 when x = -3, we need to substitute -3 in place of x and then perform the necessary calculations.
Step 1: Replace x with -3 in the expression 3x - 4
3(-3) - 4
Step 2: Simplify the expression
-9 - 4
-13
Therefore, when x = -3, the value of 3x - 4 is -13.
