Answer 2

Answer:

Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0Solve: x/a+y/b = a + b; x/a2+y/b2 =2, a, b ≠ 0
