Can someone help me how would you eliminate the “y”
saw5 [17]

Answer:

Multiply by 3 -> 3(x - y = 6)

Step-by-step explanation:

Cuz since the 2nd is positive 3y

u need a negative 3y to get rid of it

3(x - y = 6)

2x + 3y = 7

3x - 3y = 18

2x + 3y = 7

5x/5 = 25/5

x = 5

5 - y = 6

-5          -5

-y/-1= 1/-1

y = -1

(5,-1)

The perimeter of a rectangle is 99 ft, and the length is twice the width. what are its dimensions?
Bas_tet [7]

The dimension of the length and width of the rectangle with the given perimeter are 33ft and 16.5ft respectively.

<h3>What are the dimensions of the rectangle?</h3>

Perimeter of rectangle is expressed as;

P = 2( l + w )

Given that;

  • Perimeter P = 99ft
  • Let width w = x
  • Length l = 2x

We substitute into the formular above.

P = 2( l + w )

99ft = 2( x + 2x )

99ft = 2x + 4x

99ft = 6x

x = 99ft/6

x = 16.5ft

Width = x = 16.5ft

Length = 2x = 2( 16.5ft ) = 33ft

Therefore, the dimension of the length and width of the rectangle with the given perimeter are 33ft and 16.5ft respectively.
