Question

answer equations x+y=14,x-y=2​

Answer 1

Answer:

X=8,y=6

Step-by-step explanation:

x+y=14,x-y=2

by using ycx method

x y. 1

1 -14 1 1

-1 -2 1 -1

x/(-2-14)=y/(-14+2)=1/(-1-1)

x/-16=y/-12=1/-2

X=8,y=6

Answer 2

x + y = 14 x - y = 2

Add both equation, we get,

2x = 16

x = 8

Put value of x in any of the above equation,

8 + y = 14 | 8 - y = 2

y = 6 | y = 6
