Both x and y have to be the same numbers!
Answers
(3x + 5y = 7)×(-3)
(4x + 3y = 2)×(5)
-9x - 15y = -21
20x+15y =10 (-15y and and+15y cancels out)
11x = -11
x= -1
substitute the x we found into either original expressions
3(-1) + 5y = 7
-3 + 5y = 7
+3 -3+ 5y = 7+ 3
5y = 10
y=2

P:y=ax²+bx+c is the equation.
(0,3)∈P==>3=a*0+b*0+c==>c=3
(1,4)∈P==>4=a+b+3==>a+b=1 (1)
(-1,-6)∈P==>-6=a-b+3==>a-b=-3 (2)
(1)+(2)==>2a=-2==>a=-1
(1)==>b=1-(-1)==>b=2
y=x²+2x+3
y=(x+1)²+2

divide both sides by -3
f(x) = –x – 1
f(x) = –x + 3
f(x) = –x + 13

subtract 7 from both sides and it becomes -7
y=-(x+6)-7
simplify by y=-x-6-7
y = -x-13
the f(x)=-x+13 could be correct if it was written as f(x) = -(x+13)
Answer:
It should be A since the problem has a -2/3 in the equation so that makes it y+7=-2/3(x+6) and the answer should be f(x)=-2/3x-11.
