Solve this equation. Show all steps please. Will give brainliest to the first serious response.

Step-by-step explanation:

7x - 2(7x - 9) = 2(-6x + 4)                      Remove the brackets on both sides.

7x - 14x + 18 = -12x + 8                         Combine like terms

-7x + 18 = -12x + 8                                Add 12x to both sides

-7x+12x + 18 = 8                                   Combine like terms on the left

5x + 18 = 8                                           Subtract 18 from both sides

5x = 8 - 18

5x = -10                                                Divide by 5

x = - 10/5

x = - 2                                                                                                                                                                                                                                                     Proof

LHS

7*-2 -2(7*-2 - 9)                                                                                                      -14 - 2*(-14 - 9)                                      

-14 -2 (-23)

-14 + 46

32

RHS

2(-6*-2 + 4)

2(12 + 4)

32

answer: the answer is c.

step-by-step explanation:

she’s dividing 1/3 of the flour into 2 jars.

hope this : )

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)
