The solution of the equations is (-2, -1)

<h3>System of equation:</h3>

2x - 3y = -1

11x - 9y = -13

Using elimination method let multiply the first equation by -3.

Therefore,

-6x + 9y = 3

11x - 9y = -13

5x = -10

x = -10 / 5

x = -2

let's find y as follows;

2(-2) - 3y = -1

-4 - 3y = -1

-3y = -1 + 4

-3y = 3

y = 3 / -3

y = -1

Sedbober [7]

Answer:

The window should be positioned 4 1/8 feet far from each edge of the wall.

Step-by-step explanation:

Since a construction crew is placing a square in a wall for a new window, which is 3 1/8 feet wide, while the wall has a length of 11 3/8 feet, and the crew wants to position the window at the center of the wall, to determine how far from each edge of the wall should the window be positioned, the following calculation must be performed:

1/8 = 0.125

3/8 = 0.375

(11,375 - 3,125) / 2 = X

8.25 / 2 = X

4.125 = X

Therefore, the window should be positioned 4 1/8 feet far from each edge of the wall.

The correct answer is: [C]:  " $\frac{7}{18}$ " .
____________________________________________________
Explanation:
____________________________________________________
Given:
____________________________________________________

2 / (9x) = 4 / 7 ; solve for "x" ;
____________________________________________________

Cross-multiply:

→ (9x)*4 = 2 * 7 ;

  → 36x = 14 ;

Divide each side of the equation by "36" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 36x / 36 = 14 / 36 ;

x = 14/ 36 ;

  → x = 14/36 = (14÷2) / (36÷2) = 7/18 ;
______________________________________________________

The answer is: " $\frac{7}{18}$ " ;

→ which is: Answer choice: [C]: " $\frac{7}{18}$ " .
