Evaluate 3x when x = -6
To evaluate 3x when x = -6, we substitute -6 for x in the expression 3x and calculate the result.
3x = 3(-6) = -18
Therefore, when x = -6, 3x equals -18.
Evaluate -8x when x = -5
To evaluate -8x when x = -5, we substitute -5 for x in the expression -8x and calculate the result.
-8x = -8(-5) = 40
Therefore, when x = -5, -8x equals 40.
To evaluate 3x when x = -6, you simply substitute -6 for x in the expression 3x.
Now, substitute -6 for x:
3(-6)
Multiply 3 by -6:
-18
Therefore, when x = -6, 3x is equal to -18.
