Answer:

[tex]x=5,y=10[/tex]

Step-by-step explanation:

Given:

                      [tex]4x - 2y = 0[/tex]        equation:1

                 [tex]-x - 2y = -25[/tex]        equation:2

Terminating the equations by subtracting equation:2 from equation:1

                     [tex]4x - 2y -(-x - 2y)= 0-( -25)\\\\ 4x-2y+x+2y=25\\\\5x=25\\\\x=5[/tex]

Putting 'x' in equation :1

                                [tex]4(5) - 2y = 0\\\\20-2y=0\\\\2y=20\\\\y=10[/tex]

[tex]x=5,y=10[/tex]
