Letter to my mom telling her about my performance in school

hi, my name is Mrs. teacher and i was just notifying you that your son has been doing his absolute best job in class, he hardly interrupts and is always participating. i also wanted to let you know that next week is the parent teacher in person meetings that we have rescheduled due to the change of teachers on campus and this whole pandemic situation.

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

this like a whole essay
