Question

r-16=81 solve the equation

Answer 1

Answer: r = 97

Step-by-step explanation: To solve for r in this equation, we want to get r by itself on the left side of the equation.

Since 16 is being subtracted from r, to get r by itself, we need to add 16 to the left side of the equation. If we add 16 to the left side, we must also add 16 to the right side.

Notice that on the left side, -16 and +16 cancel each other out so we're simply left with r. On the right side, 81 + 16 is 97 so we have r = 97.

We can check our answer by substituting 97 back into the original equation.

So we have (97) - 16 = 81.

97 - 16 is 81 so we have 81 = 81 which is a true statement so our answer, r = 97, is correct.

Answer 2

Answer:

$\boxed{Answer: r=97}$

Step-by-step explanation:

$Hello!~Let's~solve~your~equation!$

$This~equation~is~quite~simple~actually.$

$All~you~have~to~do~is~add~16~to~both~the~sides~are~your~pretty~much~done!$

Here, let me show you :

$r-16+16=81+16$

$r=97$

And that's your answer! Have a blessed day ahead!
