Tel me you are a 7th grader without telling me you are a 7th grader

I think im cool but I'm really not. Everybody around me is trying to figure out their life. Last year was easy, we ran in the halls slappin the exit signs. We moved on and went into civics. It's really not that hard but it's not fun either. Everybody is in a relationship but i'm good with just my friends. After if finish this year I will be going on to my last year as a child.

Explanation:

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
