    A first number plus twice a second number is 7

    Let the first number be x. Let the second number be y. We're given:
    • A first number is x
    • A second number is y
    • Twice the second number means we multiply y by 2: 2y
    • Plus means we add x to 2y: x + 2y
    • The phrase is means an equation, so we set x + 2y equal to 7
    x + 2y = 7
