Question

x-y>3
x+2y<6

Answer 1

\[x-y>3........(1)\]
\[x+2y<6.........(2)\]
from (1):
\[x>y+3..........(3)\]
substitute (3) into (2) and continue from there

Answer 2

elimination method,
first: times the top equation by 2
next: eliminate the y's because they cancel each other out
next: add the rest of the equation.
then you will have x,

then you go and plug x into one of the equations and you solve for y,
then you will have (x,y)
