Show your work. -3(x+2) +5x=-9. solve and check.

x=-3/2

Step-by-step explanation:

-3(x+2)+5x=-9

-3x-6+5x=-9

2x-6=-9

2x=-9+6

2x=-3

x=-3/2

x = -3/2

Step-by-step explanation:

- 3(x + 2) + 5x = - 9

- 3x - 6 + 5x = - 9

+ 2x = - 9 + 6

+2x = -3

x = -3/2

if im undersanding the question correctly, its organized from 10

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)
