a2 x+b2 y=c2
X = (c1B2-c2b1)/(a1B2-a2b1) when solving this system of equations.
y =(c 1 a2-C2 a 1)/(b 1 a2-B2 a 1)
This is a formula for solving binary linear equations. For all binary linear equations, A 1, A2, B 1, B2, C 1 and C2 are real numbers, and this formula can be directly applied to solving binary linear equations. This is the formula method for solving binary linear equations.
