How do you solve 2/3x - 3y = 1/5 and 2x - 9y = 4?
The two lines are parallel to each other. It has no solution.
Multiply each term in equation (1) by 3
The co-efficients of x and y in the 2nd equations are 3 times the co-efficients of x and y of the 1st equation.
Moreover the equation in the general form. Its slope is given by
The slope of the 1st line is
The slope of the 2nd line is
Hence it has no solution.
