The given equation is 4x + 3y = 12

For x=0, 
4×0 + 3y = 12
⇒ 3y = 12 - 0
⇒ 3y = 12
⇒ y = 12/3 
⇒ y = 4
So (0,4) is a solution.

For x=1, 
4×1 + 3y = 12
⇒ 3y = 12 - 4
⇒ 3y = 8
⇒ y = 8/3 
So (1,8/3) is a solution.

For x=2, 
4×2 + 3y = 12
⇒ 3y = 12 - 8
⇒ 3y = 4
⇒ y = 4/3 
So (2,4/3) is a solution.

For x=3, 
4×3 + 3y = 12
⇒ 3y = 12 - 12
⇒ 3y = 0
⇒ y = 0/3 
⇒ y = 0
So (3,0) is a solution.

Four solutions are: (0,4); (1,8/3); (2,4/3); (3,0)

given that 

4x+3y = 12

if y=0, 4x+3(0)=12
               4x=12
                x=12/4
                x=3                  x=3,y=0

if y=1,4x+3(1)=12
          4x+3=12
            x=9/4                     x=9/4,y=1

if y=2,4x+3(2)=12
            4x=6
              x=3/2                     x=3/2,y=2

if y=3, 4x+3(3)=12
             4x=12-9
              x = 3/4                  x=3/4,y=3
