For what value of m will the system of equations 18x-72y+13=0 and 7x-my-17=0 have no solution?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 28

Given that

The system of equations 18x-72y+13=0 and 7x-my-17=0

For no solution condition is (a1/a2) = (b1/b2) ≠ (c1/c2)

18/72 = 7/m

m = 28
