    Add like terms

    -15c+7c=7c-15c=-8c

    we can't add the c terms and the numbers so we leave it so

    -8c+1=3-8c

    add 8c to both sides

    8c-8c+1=3+8c-8c

    0+1=3+0

    1=3

    false

    there is no solution

    Add - 15c and 7c since they have the same variable. After that you get a negative answer so you add the answer to both sides. That will cancel both numbers so it will be 1=3, the answer will be false.
