Solve the simultaneous equations5 x + 2 y = 24 3 x − 2 y = − 8 what is x what is y |
Answer» Answér :x = 2 , y = 7 Solution :Here , The given equations are ; 5X + 2y = 24 ---------------(1) 3X - 2y = -8. --------------(2) ADDING eq-(1) and (2) , we get ; => 5x + 2y + 3x - 2y = 24 + (-8) => 5x + 3x = 24 - 8 => 8x = 16 => x = 16/8 => x = 2 Now , Putting x = 2 in eq-(1) , we get ; => 5x + 2y = 24 => 5•2 + 2y = 24 => 10 + 2y = 24 => 2y = 24 - 10 => 2y = 14 => y = 14/2 => y = 7 HENCE ,x = 2 , y = 7 |
