Answered by lindsey
x is box of chalk
y is staplers

x + 2y = 10
3x + 2y = 18

solve for x and then plug in and solve for y

x+2y=10
3x+2y=18
Multiply the first equation by -1 to cancel the y's:
-x-2y=-10
3x+2y=18
Now add the rows
2x=8
x=?
Now plug that back into either original equation to solve for y.
