Answer:
1. y = 2x-4
2 y = -1/2x+3
Step-by-step explanation:
Slope intercept form of the equation is y= mx+b
where m is the slope and b is the y intercept
1. y- 2x = -4
We need to solve for y
Add 2x to each side
y -2x+2x = 2x-4
y = 2x-4
2 y-3 = -1/2 x
We need to add 3 to each side
y-3+3 = -1/2x +3
y = -1/2x+3
Take the area of the room and subtract the area of the rug.
12*10-7*5=
120-35=

This is pretty simple once you figure out the trick.
All you have to do is make the args common.
Meaning 
is nothing but 
Which is nothing but: 
.
Now using the scorpion tail method, this equation can be reframed to being: 
. You bring 6 to the other side and it'll become: 
Factorise it and you get: 
Henceforth, the solution would be 
and 
. :D
