    Let a = the lesser number.
    What expression then defines the greater number?

    If a = the lesser number then 4a + 6 represents the greater number

    The equation would then be a + (4a + 6) = 26

    Combine like terms 5a + 6 = 26
    use a (-6) on both sides of the equation to combine the constants. The resulting equation is then : 5a = 20. Using the inverse operation of multiplication, then divide both sides by 5 and the solution is a=4.

    The lesser number is 4 and the greater number is then 22.
