Coordinate form is (x,y) using the variables respectively.
2x+2y=-2
-2y
2x= -2-2y
/2
x=-1-y
9x-6y=36
9 (-1-y)-6y=36
-9-9y-6y=36
+9.
-9y-6y=45
-15y=45
/-15
y=-3
x=-1-y
x=-1- (-3)
x=2
answer: (2,-3)

Answer:
29011144
Step-by-step explanation:
Answer:
x = 2/3
DF = 10
scale factor of ΔDEF to ΔXYX is 1:3
Step-by-step explanation:
DF corresponds to XZ and DE corresponds to XY so we can set up a proportion:
6x+6/30 = 8/24
simplify 8/24 to be 1/3
6x+6/30 = 1/3
cross-multiply:
3(6x+6) = 30
18x + 18 = 30
18x = 12
x = 12/18 or 2/3
