To solve the equations: ①: ax + by = 1; ②: CX + dy = - 1 Because a misread C, we get x = - 19 / 6, y = - 3 / 2; because B misread D, we get x = - 6, y = - 19 / 7, we find the value of a and B

To solve the equations: ①: ax + by = 1; ②: CX + dy = - 1 Because a misread C, we get x = - 19 / 6, y = - 3 / 2; because B misread D, we get x = - 6, y = - 19 / 7, we find the value of a and B

Substitute x = - 19 / 6, y = - 3 / 2; X = - 6, y = - 19 / 7 into ax + by = 1 to get
（-19/6）a+（-3/2）b=1
-6a+（-19/7）b=1
The solution is a = 3, B = - 7
