y = -6   <em>Put the value of y to the second equation</em>

6x + y = 8

6x + (-6) = 8

6x - 6 = 8     <em>add 6 to both sides</em>

6x = 14     <em>divide both sides by 6</em>

x = 14/6

x = 7/3

<h3>Answer: x= 7/3 and y = -6.</h3>

Area of rectangle

Formula:

Area\,\,of\,\,rectangle=Length*Width

Putting values of length and width:

Area\,\,of\,\,rectangle=Length*Width\\Area\,\,of\,\,rectangle=(2x-9)(x+5)\\Area\,\,of\,\,rectangle=2x(x+5)-9(x+5)\\Area\,\,of\,\,rectangle=2x^2+10x-9x-45\\Area\,\,of\,\,rectangle=2x^2+x-45

So, Area of rectangle is 2x^2+x-45
