Infinitely many solutions with $(x,y)|2x-y-5=0 $ or $(x,y)|10=4x-2y$

Work Step by Step

To solve the given problem we will have to plug the simplest equation into the other equation and then solve for the other variable. $2x-y-5=0 $ or $10=4x-2y$ Now, $-4x+2y+10=0$ or, $4x-2y=10$ or, $10=10$ or, $0=0$ Hence, the given equation has Infinitely many solutions with $(x,y)|2x-y-5=0 $ or $(x,y)|10=4x-2y$
