Help please I don't understand?

Solve the system to find (u,v). Hint: x = 1/u and y = 1/v. Use x and y in the equations to solve. Once you solve for x and y, set those solutions equal to 1/u and 1/v, respectively, to find (u,v):

6/u + 5/v = 1

3/u - 10/v = 3

    solve these as simultaneous equations

    6/u + 5/v = 1

    multiply by 2

    12/u + 10/V = 2

    *********************

    3/u - 10/v = 3

    + 12/u+ 10/v = 2

    **********************

    15/u = 5

    5u = 15

    u= 3

    ***************************

    6/3 +5/v = 1

    5/v = 1-2 = -1

    -v = 5

    v= -5

    u=3, v= - 5

    check

    6/3 + (-5/5) = 1

    2 - 1 = 1

    1 =1

    3/3 - 10/(-5) = 3

    1 +2 =3

    3 =3
