    First we have to expand 5(n + 1)
    Meaning we have to multiply everything in the bracket by 5. That would mean 5n + 5.

    Now we have 5n + 5 = 2n +20

    Subtract 2n from both sides to get rid of the 2n on the right

    So you will have 3n + 5 = 20

    Now subtract 5 from both sides to get rid of the 5 on the left.

    So you will have 3n = 15

    Divide both sides by 3 to get n = 5

    Answer is n = 5

    Answer:

    n=15

    Step-by-step explanation:

    5(n+1)=2n+20

    U start by expanding the first term which will give you 5n+5

    Then after that u collect like terms giving u

    5n-2n=20-5

    Finally u evaluate it giving u

    n=15
