## chubbytots 2 years ago simplify these expression. use the distributive property to combine like terms where appropriate. a. 6(x-2)+3x b.5(2x-3y)-(x+y) anyone?? i needd help

1. Infinyte

do you need to type theese out or...?

2. Infinyte

are there choices?

3. chubbytots

nope thats the problems :)

4. Infinyte

ok then, my thoughts on this are, (for a) 9x-12

5. Infinyte

if were trying to get one answer here, it would be either 3 or -3

6. chubbytots

thats for a??

7. Infinyte

yep as for b, 9x-16y

8. chubbytots

do i have to solve them??

9. Infinyte

they would normaly be open equations, but if its part of your test, then i can find answers...

10. chubbytots

ohhh ok hmm how did u get 9x-12?? like what did you do to get them???

11. satellite73

$6(x-2)+3x$ $6x-6\times 2+3x$ $6x-12+3x$ $6x+3x-12$ $9x-12$ any question about any step?

6(x-2) is the same as 6 times x and 6 times -2. After multiplying each, you get 6x and -12. Add the 3x to the 6x to get 9x - 12.

13. chubbytots

one left o.o part B o.o

14. AJ17

5(2x-3y) is the same as (5 times 2x) + (5 times -3y), which yields 10x - 15y. Looking at the -(x+y), you get 9x - 16y when you combine them.
