    Step-by-step explanation:

    Given the expression

    3x + 2 = 4x + 5

    1. The smaller coefficient of x is 3

    to remove the smaller coefficient

    we need to add - 3x to both sides

    3x + 2 + (-3x) = 4x + 5 (-3x)

    3x + 2 - 3x = 4x + 5 - 3x

    Collecting like terms we have

    3x-3x+2 = 4x-3x+5

    2 = x + 5

    2. The constant on the right side is

    5, to remove the constant from the right side of the equation we need to add - 5 to both sides

    3x + 2 + ( - 5) = 4x + 5 + (-5)

    3x + 2-5 = 4x + 5-5

    3x-3 = 4x
