    Answer:

    The given two equations

    10x+3y=75

    6x-5y=11

    Given that we need to solve the equations using the substitution method

    1.solve the equation 1 for x=or y

    2.substitute the result in the second equation

    3.with the result, substitute in frst equation

    4. X, y obtained

    From equation 1

    10x+3y=75

    10x=75-3y

    X=75-3y/10

    Substitution x equation in 2

    6x-5y=11

    6(75-3y) /10-5y=11

    3(75-3y)/5-5y=11

    225-9y-25y=55

    225-34y=55

    225-55=34y

    170=34y

    Y=5

    3.substitute the value of y in eq1

    10x+3y=75

    10x+3(5)=75

    10x+15=75

    10x=75-15

    10x=60

    X=6

    Therefore the required solution is

    X=6

    Y=5
