Write y = 3/8 x - 2 in standard form where A, B, and C are integers whose greates common factor is 1.

3x - 8y = 2

3/8 x - y = 2

3x - 8y = 16

3x + 8y = 16

I think it's c

anonymous · Answer

= (3/8)x - 2 
 multiply through by 8: 
8y = 3x - 2 
 rewrite: 
 3x - 8y = 2

I picked that last time and got it wrong :/

oh, i dunno :/ thats what i got too!

texaschic101 · Answer

y = 3/8x - 2 (multiply by 8)
8y = 3x - 16 (subtract 3x)
-3x + 8y = - 16 (multiply by -1 to make x positive)
3x - 8y = 16

texaschic101 · Answer

you are correct...it is C

anonymous · Answer

Yay! I pretty much did everything except multiply by -1

texaschic101 · Answer

the reason I multiplied by -1 is to make x positive....you do not want a negative x
