Hiiiiiii guys please answer to this question Find the value of y​

Answer»

Answer:

x = 3  y=3/2

Step-by-step explanation:

2x+y = 2x-y = √8

squaring WHOLE equation

2∧2(x+y) = 2∧2(x-y) = 8

2∧2(x+y) = 2∧(x-y) = 2∧3

as bases are same

therefore,

2(x+y) = 2(x-y) = 2∧3

2x + 2y = 3  ------  1

2x - 2y = 3  ------2

add 1 and 2

2x + 2y + 2x - 2y = 3 + 3

2x = 6

x = 3

substitute in 2

6 - 3 = 2y

3/2 = y
