    1/2a-10b=c solve for a

    Multiply each side of the equation by 2:
    2/2a - 2(10)b = 2c

    a - 20b = 2c

    Add 20b to each side:
    a - 20b + 20b = 2c + 20b

    Cancel the 20b on the left side:
    a = 2c + 20b

    You can also factor out a 2 on the left side for another version of this answer:
    a = 2(c + 10b)
