(-3x+3y=-9)-(-3x+y=7)
-3x+3x+3y-y=-9-7
2y=-16
y=-8, making -3x+3y=-9 become:
-3x+3(-8)=-9
-3x-24=-9
-3x=15
x=-5
So the solution to this system of equations is the point (-5, -8)

Step-by-step explanation:
43000*(11/100)*4
Since they have equal bases you can subtract it like a regular number. 2-1 equals 1 so the answer would be 1/4
C^2 - d^2 / d^2 + cd - 2c^2
= cd + c^2 - 2c^2 - d^2 / d^2
= cd - c^2 - 1 (answer)
