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 |
