    Step-by-step explanation:

    Simplifying

    3.4 + 2 (9.7 + - 4.8x) = 61.2

    3.4 + (9.7 * 2 + - 4.8x * 2) = 61.2

    3.4 + (19.4 + - 9.6x) = 61.2

    Combine like terms: 3.4 + 19.4 = 22.8

    22.8 + - 9.6x = 61.2

    Solving

    22.8 + - 9.6x = 61.2

    Solving for variable 'x'.

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

    Add '-22.8' to each side of the equation.

    22.8 + - 22.8 + - 9.6x = 61.2 + - 22.8

    Combine like terms: 22.8 + - 22.8 = 0.0

    0.0 + - 9.6x = 61.2 + - 22.8

    -9.6x = 61.2 + - 22.8

    Combine like terms: 61.2 + - 22.8 = 38.4

    -9.6x = 38.4

    Divide each side by '-9.6'.

    x = - 4

    Simplifying

    x = - 4

    Step-by-step explanation:

    3.4 + 19.4 - 9.6x = 61.2

    22.8 - 9.6x = 61.2

    -9.6x = 61.2 - 22.8

    -9.6x = 38.4

    x = - 4
