Explanation:

Verses of this poem are written in iambic pentameter. ''Elegy written in a country churchyard'' is written and published by Thomas Gray in the 18th century(published in 1751 and written year earlier).

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
