The answer is R=60... yu have to subtract 10r from both sides which then leaves you with -60=-1r. From that, you divide both sides by -1 which ends to giving your answer which is r=60

Answer:

r = 60

Step-by-step explanation:

With any equation with a variable, you want to isolate the variable to find its actual value. I'll show you a step by step:

10r - 60 = 9r

Subtract 9r from both sides:

10r - 9r - 60 = 9r - 9r

Simplify:

r - 60 = 0

Add 60 to both sides to isolate r:

r - 60 + 60 = 0 + 60

Simplify:

r = 60

2. All real numbers except y = 0

3. All real numbers except x = -7

4. All real numbers except b = 10

Step-by-step explanation:

For any function to be defined at a particular value, it should not be approaching to a value $\infty$ or it should not give us the $\frac{0}{0}$ (zero by zero) form when the input is given to the function.
