X = 3 Y = 5 Or X = 5 Y = 3. More instances will be needed to ascertain the real value of x but either ways works fine ATM. 1 Like |

X² + Y² = 34 Y =√(34 - X²) since YX=15 Then √(34 - X²) * X = 15 √(34 - X²) = 15/X Taking the square of both sides 34 - X² = 225/X² Multiplying throughout by X² 34X² - X⁴ = 225 Rearranging X⁴ - 34X² + 225 = 0 Solving for X² using the quadratic formula X² = (-b ± √(b² - 4ac))/2a Where a=1, b=-34 and c=225 X² = {-(-34) ± √[(-34)² - 4(1)(225)]}/2(1) X² = 17 ± √64 X² = 17 ± 8 Hence X² = 9 or 25 Therefore X = 3 or 5 (by taking root of both sides) 1 Like |

X =3 Y=5 ans Explanation: X²+y²=34 XY=15 Therefore 3²+5²=34 9+25=34 √9=3. X=3 ans |
