i need major help bc i am not understanding this at all...its very confusing...and i am usually awesome at math....heres an example of what im working with
8x-3y=6-4x
what are you supposed to do with this equation ... i.e., directions?
What are you trying to do? What is the problem in its full extent? Please be specific
If you want to solve for either x or y, than combine like terms on either side, divide, add and subtract as nessesary
yeah i know that, i just cant get it right....can you help me out....give an explanation perhaps?
8x - 3y = 6 - 4x
What don't you understand? Putting it into standard form? Basically, you move everything to one side of the equal sign.
For finding the x-intercept, set y = 0. So from your equation, substitute y for 0 and solve for x.
For finding the y-intercept, set x = 0 and do the same thing again.
well, this is what i got, but i think im still wrong, and still confused...but this is what i got when i moved everything to the other side of the equal side.
y=-2 2/3 x + -2 - 1 1/3 x
did i get that part right?
Not quite. Looks like you need to brush up on your algebra. Also, when I said move everything to one side, I meant EVERYTHING including the y (because there's the 0 on the right side of the equation: Ax + By + C = 0).
8x - 3y - 6 = 6 - 6 - 4x
8x - 3y - 6 = -4x
...
Keep going?
What are you doing is beyond me - however I'll do another problem and you follow the same procedure.Originally Posted by c_ortiz92
13y - 9x = -3y - x - 12
step (1) bring everything to one-side
13y - 9x + 3y + x +12 = 0
step(2) collect similar terms and simplify where possible
16y - 8x + 12 = 0
step(3) simplify further -where possible- by eliminating common factor
4y - 2x + 3 = 0 ..............DONE
In general, you should not have fractions as any of the coefficients (for this form).
