    x=5

    Step-by-step explanation:

    If the equation is:

    3 (x+1) = 7 (x-2) - 3

    Solution:

    Multiply (x+1) by 3 and (x-2) by 7

    3x+3 = 7x-14 - 3

    3x+3 = 7x - 17

    Now combine the like terms:

    3+17 = 7x-3x

    20 = 4x

    Now divide both the terms by 4

    20/4 = 4x/4

    5 = x

    You can write it as x=5

    Thus the value of x is 5 ...
