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
