kx= 4
// Solve equation [1] for the variable x
[1] 6x = 24y - 30
[1] x = 4y - 5// Plug this in for variable x in equation [2]
[2] -12•(4y-5) - 24y = -36
[2] - 72y = -96
// Solve equation [2] for the variable y
[2] 72y = 96
[2] y = 4/3 // By now we know this much :
x = 4y-5
y = 4/3// Use the y value to solve for x
x = 4(4/3)-5 = 1/3 Solution :
{x,y} = {1/3,4/3}
