OpenStudy (nikolas):

Distribute the 3! (Multiply the 5 by 3 and the 8 by 3, and see what happens...)

OpenStudy (anonymous):

i distributed , but now what . dude i don't get any of this pellet .

OpenStudy (nikolas):

So what does the equation look like now?

OpenStudy (anonymous):

15-24-7 ?

OpenStudy (anonymous):

1) Solve the subtraction inside the bracket. 2) Multiply by 3 3) Subtract 7 from then number you got in step 2.

OpenStudy (nikolas):

So you've got 15-24-7... just subtract now. First find what 15-24 is. Then subtract 7 from that number.

OpenStudy (anonymous):

OpenStudy (anonymous):
