    Answer:

    x=6

    Step-by-step explanation:

    We want to find the solution to the equation:

    3x-5+2x=25

    Rearrange:

    (3x+2x)-5=25

    Combine like terms:

    5x-5=25

    We can add five to both sides:

    5x=30

    And divide both sides by five. Therefore:

    x=6

    Answer:

    x = 6

    Step-by-step explanation:

    First, combine like terms. Like terms are terms that have the same amount of like variables:

    3x – 5 + 2x = 25

    (3x + 2x) – 5 = 25

    5x – 5 = 25

    Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

    PEMDAS is the order of operation, and stands for:

    Parenthesis

    Exponents (& Roots)

    Multiplication

    Division

    Addition

    Subtraction

    First, add 5 to both sides of the equation:

    5x – 5 = 25

    5x – 5 (+5) = 25 (+5)

    5x = 25 + 5

    5x = 30

    Next, isolate the x by dividing 5 from both sides of the equation:

    (5x)/5 = (30)/5

    x = 30/5

    x = 6

    x = 6 is your solution.
