Question 191421: I need to come up with 2 equations that will have -10 as one answer and 12 as the other answer.
I start out with ax + by = c (c will be the answer -10 for one problem and 12 for the second problem.)
Help, I have no skill in algebra, my first course in over 20 years and it is very scary!!! thanks so much for the help.
Answer by jojo14344(1513) (Show Source): You can put this solution on YOUR website!

So you want to come up with 2 Line Eqns, which you are on the right track.

Let's start with the basis, Ax + By = C.

With
---> x + y = -10 (Line 1)

Also, with
---> x + y =12 (Line 2)

In (Line 1 ) we Let Fy=0:

, X-Intercept

Let Fx=0:
, Y-Intercept

We see the Line 1 in graph:
---> Line 1 with X & Y Intercepts

In Line 2, we do the same thing,
Let Fy=0:

, X-Intercept

Let Fx=0:

, Y-Intercept

We see graph,
----> Line 2 with X & Y intercepts

*In conclusion, -10 & 12 are the intercepts with A=1 & B=1

Combining Line 1 and Line 2 in the graph:
---> ;

Thank you,
Jojo
