I'm pretty sure the answer of this question is A but I just want to be positive ! * My grade is middle and the class is language arts but it doesn't give me those options so I'm just letting you know.

The main idea of a text...? -

A. is not always directly stated
B. is always stated in the first paragraph
C. usually appears in the conclusion
D. is found in the body of the text

I would think it's A too

Explanation:

The main idea is never explicitly stated in any parts of the text.

Yeah I think your right it's A

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
