 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(1512)   (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
