    Answer: 32° & 58°

    Step-by-step explanation:

    "Two angles are Complementary" means: x + y = 90

    "Sum of the 1st angle plus twice the 2nd angle is 148" means: x + 2y = 148

    Solve the system using any method (I am using elimination)

    x + y = 90 → - 1 (x + y = 90) → - x - y = - 90

    x + 2y = 148 → 1 (x + 2y = 148) → x + 2y = 148

    y = 58

    x + y = 90

    x + 58 = 90

    -58 - 58

    x = 32
