This problem can also be calculated by the idea of binary linear equations. Binary linear equation refers to an equation with two unknowns (such as X and Y), and the degree of the unknowns is 1.

Two combined linear equations with two unknowns are called binary linear equations. Each equation can be simplified to AX+BY = C. Binary linear equations are usually solved by adding, subtracting and eliminating or substituting for eliminating.
