    We can solve the expression by combining the numbers with similar signs

    3b + 5 + 2b

    Becomes,

    5b+5.

    An example:

    10 (2x + 9) + 10x - 12

    Solution.

    1. 10 (2x + 9) + 10x - 12

    2. 20x + 90 + 10x - 12

    3. 20x + 10x + 90 - 12

    Simplest form will be,

    4. 30x + 78

    5. 30x = - 78

    6. x = - 2.6
