Answer:

x=-2 and y=2

Step-by-step explanation:

Do simultaneous equations

-8x + 4y = 24 <em>(multiply everything in the equation by -7)</em>

-7x + 7y = 28 <em>(multiply everything in the equation by 8)</em>

56x - 28y  = -168

-56x + 56y = 224

<em>(add equations, ie add 'x' parts, 'y' parts, and numerical parts)</em>

<em> </em>28y = 56

∴y = 2

-8x + 4y = 24

-8x + 4(2) = 24

-8x = 16

∴x=-2

Lemme know if you have questions :D

A rectangular field is fully enclosed with 218 meters of fencing. The length of the field is
mestny [16]

The length and width of a rectangular field fully enclosed with 218 metes fencing  are 63 meters and 46 meters respectively.

The perimeter of a rectangle is the sum of the whole four sides. Therefore, the perimeter of a rectangle is defined as follows:

  • perimeter = 2(l + w)

where

l = length

w = width

perimeter = 218 meters

The length of the field is  17 meters longer than the width, w. Therefore, the length is defined as follows:

  • l = 17 + w

The length and the width can be calculated as follows:

218 = 2(l + w)

218 = 2(17 + w + w)

218 = 34 + 4w

218 - 34 = 4w

184 = 4w

divide both sides by 4

w = 184 / 4

w = 46 meters

length = 17 + 46

length = 63 meters
