Question

-3(4r-8)=-36.
HELP!!! Don’t know the answer. Btw, 8th grade homework!! ;)

Answer 1

*Sorry I messed up my math please read the new answer.
Use distrubitive property to get rid of parentheses. Multiply -3 by 4r and -8 to get -12r+24=36. Then zero out 24 by subtarcting 24 from both sides. You. should then have -12r=12. Divide by -12 on both sides to get r by itself. Your answer should be r=1*. Hope this helps :)

Answer 2

Hey there!

Firstly, we have to
`distribute`

`-3(4r)`
`+(-3)`
`(-8)`
`= -36`

`-3(4r)`
`= -12r`

`(-3)(-8)`
`= 24`

`-12r`
`+ 24`
`= -36`

Secondly, we have to
`subtract` by
`24` on each of your sides

`-12r`
`+24`
`-24`
`= -36`
`-24`

Cancel :
`24 - 24` because it'll give you the result of
`0`

Keep:
`-36`
`- 24` because it will help us solve for the value of
`r`

`-36`
`- 24`
`= -60`

`-12r`
`=`
`-60`

Thirdly we have to
`divide` by
`-12` on each of your sides

`(-12r)/(12)`
`=`
`(-60)/(-12)`

Cancel:
`(-12r)/(-12)` because it gives you the answer of
`1`

Keep:
`(-60)/(-12)` because it gives you the answer of
`r` which is
`5`

So, therefore the answer of this question
`r = 5`

Good luck on your assignment and enjoy your day!
