Asked by Sam

Can I get help on just 3 questions?
-6x + (1 - 3x) x 8
(r-1) x -3 - 3
(n-4) x -7 +7
Thanks
Answered by Ms. Sue
Are your x's multiplication signs or unknowns?

We use * to indicate multiplication.

Answered by Sam
Multiplication signs. Sorry :(
Answered by Ms. Sue
-6x + (1 - 3x) x 8 -- Doesn't make sense.

(r-1) x -3 - 3 = -6r + 6

(n-4) x -7 +7 = 0
Answered by Sam
umm.. it is -6x + (1 - 3x) * 8
Answered by Ms. Sue
Why do you have a multiplication sign and an addition sign next to each other?

-6x +
Answered by Sam
The x is a variable put into the equation so it would be -6x + (plus) (1 - 3x) * 8
