3x + 4y = 12
(i) Put x = 0,
3(0) + 4y = 12
4y = 12
y = 3
(0,3) is a solution
(ii) Put y = 0,
3x + 4(0) = 12
3x = 12
x = 4
(4,0) is a solution.
(iii) Put x = 1,
3(1) + 4y = 12
3 + 4y = 12
4y = 9
y = 9/4
(1,9/4) is a solution.
(iv) Put y = 1,
3x + 4(1) = 12
3x + 4 = 12
3x = 8
x = 8/3
(8/3,1) is a solution.
