solve it for the form:
Ax + By = C
or maybe some texts have it as:
Ax + By + C = 0
I don't understand, and I need explain to my kid step by step...
Not the answer you are looking for? Search for more explanations.
you essentially have:
sort it out with some algebra if need be into the format:\[ax+by=c\]
that C is not spose to represent the same number, its just a general constant in either case
what about the minus?
sorry I a mom, long time ago out the school :(
Standard form is Ax + By = C
your equation : y = - 2/3x + 7
you have to rearrange your equation to match the standard form
y = - 2/3x + 7 (add 2/3x to both sides)
2/3x + y = -2/3x + 2/3x + 7 (combine like terms)
2/3x + y =7
A = 2/3
B = 1
C = 7
Any questions ?
thanks thanks a lot, this was complicated for me. I understand better thank you very much. & does the answer have a minus?
no.....the answer does not have a minus......if you have anymore questions, please feel free to ask :)
i do and my answer give 2x + 3y = 21 maybe i have something wrong :(
oh...ok....2/3x + y = 7......I forgot, x cannot be a fraction.
So, to get rid of the fraction, you have to multiply everything by the denominator of the fraction, which is 3.
2/3x + y = 7
(3)2/3x + (3)y = (3)7
The 3's cancel out leaving you with 2x and 3 *y = 3y and 3*7 = 21
put it all together and you have : 2x + 3y = 21
A = 2
B = 3
C = 21
Sorry about that.....Do you understand ?
