  3. T+T + 12 = 38
    2T +12 = 38
    38-12 = 26
    2T = 26
    2/26 = 13
    T = 13

  7. Step One
    Toy Trucks = x
    Toy Cars = x+12 (because there are 12 more toy cars than toy trucks in a toy box)
    Total total of toy cars and trucks = 38

    Step Two
    equation = x + x + 12 = 38
    2x + 12 = 38

    Step Three
    Keep 2x as it is but use 12 to - (minus) from +12 and 38
    Which will look like this
    2x + 12 = 38
    -12 -12
    The 12 after 2x automatically get canceled out because they are same numbers.
    What remains is 2x = 26 (just to show you calculation 38-12 =26)

    Step three
    x = 26
    ----- (divide)
    Answer is 13
