Tìm: 8b-9a=31 tìm a;b

To find the values of a and b, we need to solve the equation 8b - 9a = 31.

There are multiple possible solutions for a and b, as this is a linear equation with two variables.

One possible solution is:
a = 3
b = 5

To check if these values are correct, substitute them back into the equation:
8(5) - 9(3) = 40 - 27 = 13, which is not equal to 31.

Therefore, there are no integer solutions for a and b that satisfy the equation 8b - 9a = 31.
