How would you write an equation that would allow someone to find the value of r?

You're equation will look like:

R = 1167 + 1167 + 1167 - 239

To get the answer, simplify

R = 1167 + 1167 + 1167 - 239 = 3262

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
