    7 (y + 3) = 5y + 8

    7. y + 7.3 = 5y + 8

    7y + 21 = 5y + 8

    7y - 5y = 8 - 21

    2y = - 13

    y = - 13/2

    Answer: - 6.5

    Step-by-step explanation:Simplifying

    7 (y + 3) = 5y + 8

    Reorder the terms:

    7 (3 + y) = 5y + 8

    (3 * 7 + y * 7) = 5y + 8

    (21 + 7y) = 5y + 8

    Reorder the terms:

    21 + 7y = 8 + 5y

    Solving

    21 + 7y = 8 + 5y

    Solving for variable 'y'.

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

    Add '-5y' to each side of the equation.

    21 + 7y + - 5y = 8 + 5y + - 5y

    Combine like terms: 7y + - 5y = 2y

    21 + 2y = 8 + 5y + - 5y

    Combine like terms: 5y + - 5y = 0

    21 + 2y = 8 + 0

    21 + 2y = 8

    Add '-21' to each side of the equation.

    21 + - 21 + 2y = 8 + - 21

    Combine like terms: 21 + - 21 = 0

    0 + 2y = 8 + - 21

    2y = 8 + - 21

    Combine like terms: 8 + - 21 = - 13

    2y = - 13

    Divide each side by '2'.

    y = - 6.5

    Simplifying

    y = - 6.5
