Answer:

(3,3)

x=3 and y=3

Step-by-step explanation:

The system of equations are:-

3x - y = 6

6x + y = 21

Elimination method: To eliminate one variable by add/sub both equation and solve for another variable.

3x - y = 6

6x + y = 21

Add both equation and eliminate y

3x + 6x = 6 + 21

       9x = 27

          x = 3

Put x=3 into 6x + y = 21

6(3) + y = 21

18 + y = 21

      y = 21 - 18

      y = 3

Hence, The solution of the system of equations is (3,3)

For a given set of rectangles, the length is inversely proportional to the width. In one of these rectangles, the length is 12 a
RSB [31]

Answer:

The width is 8 units

Step-by-step explanation:

This is a variation problem we are to work with.

Length is inversely proportional to width, let length be l and width be w

modeling the statement mathematically, we have lw = k where k is the proportionality constant

Now let’s get k from l = 12 and w = 6

k = 12 * 6 = 72

Now for the second rectangle also;

lw = k given l = 9

9w = 72

w = 72/9

w = 8
