Select whether each equation has no solution, one solution, or infinitely many solutions. No solution

One solution

Infinitely many solutions

A)5x−7=5x

B)3x−9=3(x−3)

C)2x−6=−2(x−3)

D)2x+6−5x=−3(x−2)

are you in algebra 1? i have trouble on this to, try simplifying both sides of the equation as best as you can, maybe that could help

answer: i believe its b. if you sound out the sentences that sounds wrong.

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)
