evaluate 7x-3x for x=6

7x-3x

(7*6) - (3*6) = 42 - 18 = ?

24 is that right or do i leave ?

That's right.

To evaluate the expression 7x - 3x for x = 6, we substitute 6 for x and perform the calculations.

First, let's substitute x = 6 into the expression:

7(6) - 3(6)

Next, we simplify the expression by performing the multiplication:

42 - 18

Finally, we perform the subtraction to get the final result:

24

Therefore, when x = 6, the expression 7x - 3x evaluates to 24.
