    Our two numbers are 50 and 20

    Step-by-step explanation:

    Sum means add together

    Difference means subtract each other

    x + y = 70

    x - y = 30

    subtract from each other

    2x = 100

    divide both sides by 2

    x = 50

    our first number is 50

    50 + y = 70

    subtract both sides by 50

    y = 20

    Our two numbers are 50 and 20
