r = -9
Step-by-step explanation:
in order to evaluate for the value of R , the first step to do is to cross multiply and then combine the like terms together.
solution
-27/9=R/3
we are going to cross multiply
-27 x 3 = 9 x R
-81 = 9R
divide both sides by the coefficient of R which is 9
-81/9 = 9r/9
-9 = r
therefore r = -9
therefore the value of R in the expression is evaluated to be equals to -9
