Two solutions are (3, 0) and (0, -7). Substituting y = 0 gives 7x = 21, so x = 3. Substituting x = 0 gives -3y = 21, so y = -7.

Class 9 Maths Ganita Manjari Part 2 chapter 13 Two Variables, One Line solutions
Two solutions for the equation 7x – 3y = 21 are (3, 0) and (0, -7). Setting y = 0 gives 7x – 3(0) = 21, which simplifies to 7x = 21, leading to x = 3. Setting x = 0 gives 7(0) – 3y = 21, which simplifies to -3y = 21, yielding y = -7. Both pairs satisfy the given equation.
