    x, y = 2,1

    Step-by-step explanation:

    3x+4y=10 ... equ1

    x-y=1 ... equ2

    This system of equations forms a quadratic equation.

    Lets use the substitution method in solving this set of equations

    from equ 2; x=y+1

    substitute x=y+1 into equ 1

    3 (y+1) + 4y=10

    3y+3+4y=10

    7y=10-3

    7y=7

    y=7/7

    y=1

    but x=y+1

    substitute the value of y into this equation to get x

    x = 1+1

    x=2

    x, y=2,1
