Elimination method using addition and subtraction x-y=2 and x+y=-3

x=-1/2, y= -5/2

Step-by-step explanation:

x-y=2

x+y=-3

Add these together to eliminate y

x-y=2

x+y=-3

2x = -1

2x/2 =-1/2

x = -1/2

Now we need to find y

x+y = -3

-1/2 +y = -3

Add 1/2 to each side

-1/2 +1/2+y = -3+1/2

y = -6/2+1/2

y =-5/2

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
