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

$\frac{-12r}{12}$ $=$ $\frac{-60}{-12}$

Cancel: $\frac{-12r}{-12}$ because it gives you the answer of $1$

Keep: $\frac{-60}{-12}$ 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!
