Solve the following systems of equations:x + 2y = \(\frac{3}{2}\)2x + y = \(\frac{3}{2}\) |
|
Answer» x + 2y = \(\frac{3}{2}\) ⇒ 2x + 4y = 3 …(i) 2x + y = \(\frac{3}{2}\) ⇒ 4x + 2y = 3 …(ii) Multiplying eq2 by 2 and subtracting from eq1 2x + 4y – 8x – 4y = 3 – 6 ⇒ - 6x = - 3 ⇒ x = 1/2 Thus, 2 × 1/2 + 4y = 3 ⇒ y = 1/2 |
