To find the value of the expression -x + 3x - 2 when x is equal to 3, you can substitute the value of x into the expression and simplify:
-3 + 3(3) - 2
Now, perform the calculations step by step:
-3 + 9 - 2
Now, add and subtract:
-3 + 9 = 6
6 - 2 = 4
So, when x is equal to 3, the expression -x + 3x - 2 equals 4.
