You can put this solution on YOUR website!Complete the ordered pairs sot that each is a solution for the given equation.
(0, ),( ,3/4),( ,0),(8/3, )
3x+4y=12
1. 3(0)+4y=12
4y=12
y=3
2. 3x+4(3/4)=12
3x+1=12
3x=11
x=11/3
3. 3x+4(0)=12
3x=12
x=4
4. 3(8/3)+4y=12
8 +4y=12
4y=4
y=1

You can put this solution on YOUR website! The first number on the ordered pair represent the x value and the second represent the y value. Substitute the the given info in the equation 3x + 4y =12 to sove for the other value.
3(0)+4y=12
0+4y =12
4y/4 = 12/4
y=3
(0,3)
3x + 4(3/4) =12
3x + 12/4 =12
3x + 3 -3 =12 - 3
3x = 9
3x/3 =9/3
x = 3
(3,3/4)
3x + 4(0)=12
3x +0 =12
3x/3 =12/3
x=4
(4,0)
3(8/3) + 4y = 12
24/3 + 4y =12
8 + 4y -8 = 12-8
4y = 4
4y/4 =4/4
y = 1
(8/3,1)
(0,3)(3,3/4) (4,0) (8/3,1)
Hope this help
