    Simplifying

    4p + - 40 = 7 (2p + 2)

    Reorder the terms:

    -40 + 4p = 7 (2p + 2)

    Reorder the terms:

    -40 + 4p = 7 (2 + 2p)

    -40 + 4p = (2 * 7 + 2p * 7)

    -40 + 4p = (14 + 14p)

    Solving

    -40 + 4p = 14 + 14p

    Solving for variable 'p'.

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

    Add '-14p' to each side of the equation.

    -40 + 4p + - 14p = 14 + 14p + - 14p

    Combine like terms: 4p + - 14p = - 10p

    -40 + - 10p = 14 + 14p + - 14p

    Combine like terms: 14p + - 14p = 0

    -40 + - 10p = 14 + 0

    -40 + - 10p = 14

    Add '40' to each side of the equation.

    -40 + 40 + - 10p = 14 + 40

    Combine like terms: - 40 + 40 = 0

    0 + - 10p = 14 + 40

    -10p = 14 + 40

    Combine like terms: 14 + 40 = 54

    -10p = 54

    Divide each side by '-10'.

    p = - 5.4

    Simplifying

    p = - 5.4

    p=3

    Step-by-step explanation:

    4p-40=7 (-2p+2)

    4p-40=-14p+14

    -40=-18p+14

    -54=-18p

    p=3
