Answer 1

HOPE IT HLEPS 2 U .....✌️✌️

X = 10 AND Y = 6

Answer 2

Answer:

x = 10

y = 6

Step-by-step explanation:

This can be solved using various ways

1) Trial and Error Method

RHS = 16 ; 4

LHS = x + y ; x - y

let x be 1, y be 15

x+y = 1+15 = 16

x - y = 1 - 15 = -14

LHS ≠ RHS

let x be 9, y be 5

x - y = 9 - 5 = 4

x + y = 9 + 5 = 14

LHS ≠ RHS

let x be 10, y be 6

x + y = 10 + 6  = 16

x - y = 10 - 6 = 4

LHS = RHS

2) By adding both the equation

(x + y) + (x - y) = 16 + (4)

2x = 20

x = 10

y = 16 - x = 16 - 10 = 6

x = 10

y = 6
