Coordinates for N (-3,-3)
This is assuming that the question laid out the sequence of a calculation.
4y x 3y + z = 100
12y^2 + z = 100
Answer:
(-9,-3.4)
Step-by-step explanation:
By adding 2.1x and subtracting 5.3 from the top equation, it will end up as 2.1x=4y-5.3
By adding 5.5y to the bottom equation, it will end up as 2.1x=5.5y-0.2.
By the equal valuesmethod, they are equal: 5.5y-0.2=4y-5.3
5.5y+5.1=4y
5.1=-1.5y
y=-3.4; this gets us our y-coordinate.
To get the x-coordinate, you plug the value for y back into the original equation.
-2.1x-4y=5.3
-2.1x-4(-3.4)=5.3
-2.1x-13.6=5.3
-2.1x=18.9
x=-9
