decide on some values for x and y , say,
x = -3, y = 5
now make up any two combinations for x and y
say,
1. 3x + 2y = .... evaluate this using our values for x and y
3(-3) + 2(5) = 1
so the first equation is 3x + 2y = 1
2. 4x - 3y = ....
4(-3) - 3(5) = -27
then 4x - 3y = -27
so 3x + 2y = 1 and
4x - 3y = -27 must have solutions x=-3, y=5
I will leave it up to you to actually solve it.
As you can see, there would be an infinite number of pairs of equations for just those two values I picked.
Of course you could have picked any other values of x and y.
I would appreciate any help thanks
select two intergers between
-12 and +12 write two equations that have the two intergers as solutions. solve the equation using addition/subtraction method
