Choose the answer based on the most efficient method as presented in the lesson. if the first step in the solution of the equation -9 + x = 5x - 7 is "subtract x," then what should the next step be? subtract 5x add 7 add 9 divide by 4

add 7

Step-by-step explanation:

The equation given is a multi-step equation:

-9 + x = 5x - 7

In order to isolate the variable and solve, you need to use inverse (opposite) operations to get the variable on one side and the numbers on the other.  As given, the first step is to 'subtract x' from both sides:

-9 + x = 5x - 7

    - x     - x

     -9 = 4x - 7

Next step would be to 'add 7' on both sides:

    -9 = 4x - 7

  +7       +7

   -2 = 4x

Last step would be to 'divide 4' on both sides:

  -2 = 4x

   4     4

   -1/2 = x

add 7

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
