2x + y - 10 = 0 ==>  2x + y = 10
x - y - 4 = 0 ==> x - y = 4

so now we have :
2x + y = 10
x - y = 4
-----------------add
3x = 14
x = 14/3

x - y = 4
14/3 - y = 4
-y = 4 - 14/3
-y = 12/3 - 14/3
-y = -2/3
y = 2/3 <==

Answer:

2/3

Step-by-step explanation:

2x + y - 10 = 0 ==>  2x + y = 10

x - y - 4 = 0 ==> x - y = 4

so now we have :

2x + y = 10

x - y = 4

-----------------add

3x = 14

x = 14/3

x - y = 4

14/3 - y = 4

-y = 4 - 14/3

-y = 12/3 - 14/3

-y = -2/3

y = 2/3 <==
