In this line from Walt Whitman's poem "I Hear America Singing," personification is used.

Personification is a figure of speech, or indirect way of conveying an idea, that represents a non-human thing as if it were human so as to give human qualities or traits to it, often by way of a metaphor.

In this case, when Whitman wrote "I hear America singing", he gave America a quality of human beings, that is the possibility to sing.

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4
