    8n-25=15+3n

    Step-by-step explanation:

    We can do this by working backwards and making suitable substitutions.

    If n=8

    Multiply both sides of the equation by 5

    5n=8*5

    5n=40

    Now, we can rewrite the two sides of the equation as follows

    5n=8n-3n 40=25+15

    Thus:

    5n=40 is equivalent to:

    8n-3n=25+15

    Add 3n to both sides

    8n-3n+3n=25+15+3n

    8n=25+15+3n

    Subtract 25 from both sides

    8n-25=25-25+15+3n

    We have:

    8n-25=15+3n

    Solving this equation will have a solution of n=8.
