Step-by-step explanation:
2x-y=0
4x-2=2
-----------
y=2x-0
y=2x
-------------
4x=2+2=4
4x=4
x=4/4=1
---------------
y=2(1)=2
x=1, y=2.
Answer:
Coordinate of Point A is (-11, 15)
Step-by-step explanation:
M -- (-3, 7)
B -- (5, -1)
Therefore, (5 + x)/2 = -3
x = -11
(-1 + y)/2 = 7
y = 15
Therefore Point A is (-11, 15)
