Complete the order pairs so each is a solution for the given equation
3x + 4y = 12
these are the numbers
( ,3) ( ,3/4) ( ,0) and (8/3, )
need to fill in the missing numbers

#3 ( ,0).
3x + 4y = 12. The problem is asking for the x value when y is .
3x + 4*0 = 12
3x + 0 = 12
3x = 12
x = 4
The others are done the same way. Fractions make it a little more difficult but generally the fraction can be modified by multiplying the equation through by the denominator.
