My question is r/24=-3


The answer:

r/24 = -3


to solve for r, multiply each side of the equation by 24

(r/24)*24 = (-3)*24

r*(24/24) = (-3)*24

r*(1) = (-3)*24

r = (-3)*24

r = -72

the final answer is: r = -72


check the solution by substituting -72 for r in the original equation:


r/24 = -3

(-72)/24 = -3

-3 = -3, OK → r = -72 is a valid solution



Thanks for writing.
