Someone who knows some math please help me!

Patheticly easily!!

x-5y=2
2x+y=4

x=2+5y

2(2+5y)+y=4
4+10y+y=4
11y=0
y=0

to find X

2x+y=4

substitute in for y

2x+0=4
2x=4
x=2

check for both equations

x-5y=2

2-5(0)=2
2=2 (first equation is true)


2x+y=4

2(2)+0=4
4=4

last equation is true



Now you better kiss my ass for waisting my time doing this.
