Maria is summarizing article she read for science class what information should she included her summary

She should include what she has learned from it and what the main idea of the article is so she does not have to explain herself for the whole article.

Explanation:

the most important details or main ideas

Explanation:

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
