    y = - 319/20| x = 377/20

    Step-by-step explanation:

    /| 7/2-x-y - (3/5) = 0| - 11*x - (13*y) = 0

    We try to solve the equation: 7/2-x-y - (3/5) = 0

    29/10-x-y = 0 / / - 29/10-x

    -y = - (29/10-x) / / * - 1

    y = 29/10-x

    We insert the solution into one of the initial equations of our system of equations

    We get a system of equations:

    /| - (13 * (29/10-x)) - 11*x = 0| y = 29/10-x

    -1*13 * (29/10-x) - 11*x = 0

    2*x-377/10 = 0

    2*x-377/10 = 0 / / + 377/10

    2*x = 377/10 / / : 2

    x = 377/10/2

    x = 377/20

    We insert the solution into one of the initial equations of our system of equations

    For y = 29/10-x:

    y = 29/10-377/20

    y = - 319/20

    We get a system of equations:

    /| y = - 319/20| x = 377/20
