y=-4-x
y=2x-1
-4-x=2x-1
3x=-3
x=-1
y=-3
The type of equation is consistent because they intersect at ( -1,-3 )
You subtract negative 4 and negative 12...think in a number line and you find negative 4 and then you decrease( which means you move to your left of the number line) and find negative 12 and then you count the spaces you took to get to negative 12
150 to 60. But the more commen why to do that were to simplify it.
