What are the coordinate points (x, y) of
y-2x =3
-x= y-9
PLEASE HELP

  (x,y) = (2,7)

Explanation:

-x = y-9 turns into x = -y+9 when you multiply both sides by -1

Plug this into the first equation y - 2x = 3 to get the following

y - 2x = 3

y - 2( x ) = 3

y - 2(-y+9) = 3 ... replace x with -y+9

y + 2y - 18 = 3

3y - 18 = 3

3y = 3+18

3y = 21

y = 21/3

y = 7

Which then tells us,

x = -y+9

x = -7+9

x = 2

So x = 2 and y = 7 pair up to get the solution (x,y) = (2,7)

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
