Question
For what value of m will the system of equations
18x-72y+13=0 and 7x-my-17=0 have no solution?Solution
ATQ, To have no solution, the two equations should represent parallel lines. We can rewrite the equations in slope-intercept form: 8x - 72y = 13 --> y = (8/72)x - 13/72 --> y = (1/9)x - 13/72 7x - my = 17 --> y = (7/m)x - 17/m For the lines to be parallel, their slopes must be equal. So we set (1/9) = 7/m and solve for m: 1/9 = 7/m m = 63 Therefore, the value of m for which the system of equations has no solution is m = 63.
