Answer 2

Step-by-step explanation:

let, 2 x - y = 2........eq.1

     5 x + 2 y = 14.........eq.2

multiply eq.1 by 2,

                             4 x - 2 y = 4.......eq.3

by elimination method.....eq.2 + eq.3

5 x + 2 y = 14

4 x - 2 y = 4

9 x = 18

x = 2

substitute x = 2 in eq.1

2*2 - y = 2

4 - 2 = y

y = 2

∴ x + y = 4
