The two equations are : x+x+y=22 = **2x+y=22 (i)**

y+y+x=20 =**2y+x=20 (ii)**

From equation (i) we have,

2x+y=22

= y=22-2x

**Putting this value in equation (ii) we get,**

2y+x=20

= 2(22-2x)+x=20

= 44-4x+x=20

= -3x=20-44

= -3x=-24

= 3x=24

= x=24/3 = 8

**Now,we know from equation (i),**

2x+y=22

= 2x8+y=22

= 16+y=22

= y=22-16 = 6

**Thus, x=8 and y=6**

y+y+x=20 =

From equation (i) we have,

= y=22-2x

= 2(22-2x)+x=20

= 44-4x+x=20

= -3x=20-44

= -3x=-24

= 3x=24

= x=24/3 = 8

= 2x8+y=22

= 16+y=22

= y=22-16 = 6
