How to solve the binary linear equation? Tell me the method. The teacher hasn't taught you.

3x+ 1y = 22 Multiply both sides by 4 to get 4y+ 12x=88.

4y+ 12x=88 and 4Y+ 1x = 22 are respectively subtracted to get 1 1x=66, so x = 6;

Bring x=6 to 3x+ 1y = 22 and get y=4.

To sum up:

First make the coefficient of one of the unknowns the same, and then subtract the two expressions to eliminate an unknown, which is the same as solving a linear equation.
