Iknow this is not a real question but i was wondering how to mark someone brianliest? is it like a button u click or what?
heres a hundred points if u answer pls tell me

idk either tbh, but if you get like two answers on your question you mark brainliest for the one you find the most useful

it shows up for you on either one

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
