1/x + 1/4 = 7/12 solve for x

Licemer1 [7]

Given equation is
$\frac{1}{x} + \frac{1}{4} = \frac{7}{12}$

We can solve it by subtracting 1/4 both side
$\frac{1}{x} + \frac{1}{4} - \frac{1}{4} = \frac{7}{12} - \frac{1}{4}$

$\frac{1}{x} = \frac{7}{12} - \frac{1}{4}$
                          $= \frac{7 - 3}{12}$
                          $= \frac{4}{12}$
                          $= \frac{1}{3}$

So $\frac{1}{x} = \frac{1}{3}$
On comparing x = 3.

SO the solution of equation is x = 3

At what ordered pair is "Parking Lot B" located at?

Arlecino [84]

The ordered pair of the parking lot is the coordinates of the lot in the coordinate plane

Parking lot B is located in the ordered pair (-3,4)

<h3>How to determine the ordered pair of lot B</h3>

From the figure, we have the following highlights

Parking lot B is located at x = -3 on the horizontal axis, and it is located at y = 4 on the vertical axis.

So, we have:

(x,y) = (-3,4)

Hence, parking lot B is located in the ordered pair (-3,4)
