Which of the following lines is not written in iambic pentameter? A. When I see birches bend to left and right

B. But thy eternal summer shall not fade

C. I lift my lamp beside the golden door!

D. One foot down, then hop! It’s hot.

what is the context here? we need to know what story you're talking about : )

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
