Which answer shows this equation written in standard form?



9 – 4(x – y) = –6x + 6



A.


2x + 4y = 3


B.


2x + 4y = –3


C.


2x – 4y = 3


D.


–10x + 4y = –3



Answer :

so first we solve and simplify

first parenthasees

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)
