Work Shown:

The result is approximate since
is approximate.
So first we solve and simplify

9-4(x-y)=-6x+6
distribute using distributeive property of multiplication which is a(b+c)=(ab)+(ac)
so -4(x-y)=-4x+4y
9-4x+4y=-6x+6
add 6x to both sides
9+2x+4y=6
subtract 9 from both sides
2x+4y=-3
only B matches this
B is the correct answer
(I don't know what standard form is but I know what simplified is)
Answer:
X= 2
Step-by-step explanation:
6(x-4) + 7 = -5 First you distribute the 6
6x - 24 + 7 = -5 Then add like terms
6x -17 = -5 then add 17 to both sides
6x = 12 then divide 12 by 6
x = 2
Answer:
it's -6 dollars per year.
