The given equation is expressed as

7x - 5 = 4y - 6

If we substitute x = 2 and y = 4 into the equation, it becomes

7 * 2 - 5 = 4 * 4 - 6

14 - 5 = 16 - 6

9 is not equal to 10

Thus, (2,4) is not a solution

If we substitute x = 3 and y = 6 into the equation, it becomes

7 * 3 - 5 = 4 * 6 - 6

21 - 5 = 24 - 6

16 is not equal to 18

Thus, (3,6) is not a solution

Thus, neither (2,4) nor (3,6) is a solution of the equation
