4x - 2y = 0<br> -x - 2y = -25

Fittoniya [83]

Answer:

$x=5,y=10$

Step-by-step explanation:

Given:

$4x - 2y = 0$ equation:1

$-x - 2y = -25$ equation:2

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

$4x - 2y -(-x - 2y)= 0-( -25)\\\\ 4x-2y+x+2y=25\\\\5x=25\\\\x=5$

Putting 'x' in equation :1

$4(5) - 2y = 0\\\\20-2y=0\\\\2y=20\\\\y=10$

$x=5,y=10$
