It is known that x = 3Y = - 2 and x = 2Y = 1 are two solutions of the quadratic equation AX + by + 3 = 0, then the analytic expression of the linear function y = ax + B is It is known that x = 3, y = - 2 and x = 2, y = 1 are two solutions of binary linear equation AX + by + 3 = 0, then the analytic expression of primary function y = ax + B is

It is known that x = 3Y = - 2 and x = 2Y = 1 are two solutions of the quadratic equation AX + by + 3 = 0, then the analytic expression of the linear function y = ax + B is It is known that x = 3, y = - 2 and x = 2, y = 1 are two solutions of binary linear equation AX + by + 3 = 0, then the analytic expression of primary function y = ax + B is

It can be seen from the meaning that x = - 2, y = - 2 / 3 and x = 1, y = 1 / 2 are two groups of solutions of AX + by + 3 = 0, which can be obtained by substituting them respectively
-2a-2b/3+3=0
a+b/2+3=0
Well organized
6a+2b=9
2a+b=-6
The solution is a = 21 / 2, B = - 27
So y = ax + B is y = 21x / 2-27
The analytical formula is 21x-2y-54 = 0
