    a = 4 + - 1.333333333b

    Step-by-step explanation:

    Simplifying

    3a + 4b = 12

    Solving

    3a + 4b = 12

    Solving for variable 'a'.

    Move all terms containing a to the left, all other terms to the right.

    Add '-4b' to each side of the equation.

    3a + 4b + - 4b = 12 + - 4b

    Combine like terms: 4b + - 4b = 0

    3a + 0 = 12 + - 4b

    3a = 12 + - 4b

    Divide each side by '3'.

    a = 4 + - 1.333333333b

    Simplifying

    a = 4 + - 1.333333333b
