Which equations have the same value of x as 5/6x+2/3=-9? select three options.

The right answer must have the same value for x.

First, we could find the value of the variable:

So, all equations that satisfy the same value for x are the same.

For example:

This is an equivalent equation.

Also,

Equivalent equation.

Similarly,

is also a equivalent equation.

All these three are equivalent because they have the same result for the variable.

Your value for x is -58/5

Step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
