Question 21009: Hi,
I do not see any dection for the problem I am asking for a solution for. According to my book this is: Complete the ordered pairs so that each is a solution for the given equation. 3x + 4y = 12 (0, ),( ,3/4),( ,0),(8/3, ).
I am not sure if I wrote the fractions correctly 3/4 and 8/3.
Thank you for your help

You can put this solution on YOUR website! well all you have to do is plug in the number for the correct varialbe and solve.
pluging 0 in for x
3(0)+4y=12
simplifying
4y=12
dividing both sides by 4
y=3
(0,3)
plinging 3/4 in for y
3x+4(3/4)=12
simplifying
3x+3=12
subtracting 3 from both sides
3x=9
dividing both sides by 3
x=3
(3,3/4)
Pluging in 0 for y you get
3x+4(0)=12
simplifying
3x=12
dividing both sides by 3
x=4
(4,0)
pluging in 8/3 for x you get
3(8/3)+4y=12
simplifying
8+4y=12
subtracting 8 from both sides
4y=4
dividing both sides by 4
y=1
(8/3,1)
