Answer:
r = 192
Explanation:
You are trying to solve for the variable, r. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 3 from both sides, then multiply 8.
Subtract 3 from both sides of the equation:
r/8 + 3 (-3) = 27 (-3)
r/8 = 27 - 3
r/8 = 24
Isolate the variable, r. Multiply 8 to both sides:
(r/8) * 8 = (24) * 8
r = 24 * 8
r = 192
r = 192 is your answer.
