Answer:
x = 1
Step-by-step explanation:
Subtract 2 from both sides
8x = 8
Divide both sides by 8
X = 1
Answer:
1) F(x)=
2) 
Step-by-step explanation:
Applying the antiderivation rules:
F(x)= 
F(x)=
Checking by differentitation we have:

Which is demonstrated.
2) To find f we must antiderivate twice:

Answer: Hope this helped(tried my best thinking what the question was asking)
x=0
y=-3
Step-by-step explanation:
(Im going to add and subtract)
Add:
14x-12y=36
14x+9y=-27
28x-3y=9
Subtract:
-14x+12y=-36
14x+9y=-27
21y=-63
y=-3 (substitute in first equation)
7x+18=18
7x=0
x=0
SO
y=-3 and x=0
