    X=number of boys.

    y=number of girls.

    We can suggest this system of equations:

    x+y=511

    y=x+165

    We can solve this system by substitution method.

    x + (x+165) = 511

    2x=511-165

    2x=346

    x=346/2

    x=173

    y=x+165

    y=173+165

    y=338

    Answer: there are 173 boys in the class.
