To solve this equation, the first thing to do would be to simplify. Look at the steps shown below.

-\frac{1}{2}x + 1 = 7x - 14

(To make things easier, I will be writing 1/2x as 0.5x)

First isolate x my moving the variables to one side of the equation and the numbers to the other. Please note that when you move them this way, the number or variable must become the opposite of what it currently is for the equation to remain true. The equation will now look like;

-0.5x - 7x = -1 - 14

--> -7.5x = -15

We know that 2 * 7 is 14. Since we have two hales, this creates a whole.

--->x = \frac{15}{7.5}

---->x = 2

The answer is A.

maxonik [38]

9514 1404 393

Answer:

  51

Step-by-step explanation:

Let s represent the number of seats in a row. Then the number of rows is (s-9) and the total number of seats is ...

  s(s-9) = 2142

  s² -9s +4.5² = 2142 +4.5² . . . . . complete the square

  (s -4.5) = √2162.25 . . . . . . . . take the positive square root

  s = 4.5 +46.5 = 51 . . . . . . . add 4.5

The number of seats in each row is 51.
