Answer:
Well, if you're talking about what operation is the variable about to be done with...then its multiplication because you're supposed to first solve the expression on the left by multiplying.
But, if you're talking about solving just look below:
−3(4r−8)=−36
(−3)(4r)+(−3)(−8)=−36 (Distribute here)
−12r+24=−36 (Subtract 24 from both sides.)
−12r+24−24=−36−24
−12r=−60 (Divide both sides by -12)
r=5
This number has a certain amount of hundreds, tens and ones. We know that there are 8 hundreds, so the number is like 8xy
Also, the tens are 2 fewer than the hundreds, so 2 fewer than 8, which is 6. The number is like 86y
The ones are also 2 fewer than the hundreds, so 2 fewer than 8, which is 6. So, the number is 866.

Answer:
Add 6 to both sides.
Step-by-step explanation:
You are trying to solve for x in this type of question. In this case, note that there is a equal sign, and that what you do to one side you do to the other. Also note that to isolate the x (your goal), you must do the opposite of PEMDAS. (Note that PEMDAS = Parenthesis, Exponent (& Roots), Multiplication, Division, Addition, Subtraction).
So your first step is to add 6 to both sides.
2/5x - 6 (+6) = -16 (+6)
Simplify. Solve:
2/5x + (-6 + 6) = -16 + 6
2/5x = -10

Finish finding for x.
Multiply the recipricol of the fraction to both sides to isolate the x. Multiply 5/2 to both sides:
(5/2)(2/5)x = (-10)(5/2)
x = (-10)(5/2)
x = (-50)/2
x = -25
x = -25 is your answer.
