Question

4x - 2y = 0
-x - 2y = -25

Answer 1

`x=5,y=10`

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`
