3/y-2 -1/y=4/y^-2y

3y/y^-2y - y/y^-2y=4/y^-2y
3y-y=4
2y=4
y=2

  • algebra 2 - ,

    Put y =2 in the original equation on each side, and see if each side equals the other side.

  • algebra 2 - ,

    y=2 should immediately be discarded, since fractions with y-2 in the denominator are not defined.

    The steps should be

    3y/y(y-2) - (y-2)/y(y-2) = 4/y(y-2)
    3y-y+2 = 4
    2y = 2
    y = 1
