Answer:

Step-by-step explanation:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

What is the solution of −81=b6 ? A. b = −486 B. b = −75 C. b = 13.5 D. b = 486

BartSMP [9]

We have to isolate b to be alone.
Soooo first we divide both sides by 6

-81 = b6
÷6 = ÷6 The right side cancels out and gets the b alone. While we solve the right side of the equal sign.
-81 ÷ 6 = -13.5
So this means we isolated b alone!
b = -13.5

Our final answer is..
b = -13.5
