    3x+7 is equal to x+5+2x+2

    Step-by-step explanation:

    3x+7 is equal to x+5+2x+2

    You can add x and 2x (x+2x) to get 3x

    Then you can add 5 and 2 (5+2) to get 7

    Therefore 3x+7 is equal to x+5+2x+2

    Step-by-step explanation:

    on the right side of the equation we can add like terms, meaning adding the x terms with the x terms (that means including their coefficients, in this case that x has a 2 in front of it), and the normal numbers with the other normal numbers. So by simplifying the right side of the equation with the x terms first we have

    x+2x=3x

    and

    5+2=7

    Thus we get

    3x+7
