    2x+y=20 and -5y=6x+12 are your equations.

    You can turn 2x+y=20 into y=-2x+20

    Substitute this value of y into the other equation.
    -5(-2x+20)=-6x+12
    10x-100=-6x+12
    16x=112
    x=7 

    Substitute this value of x into the other equation.
    2(7)+y=20
    y=6

    Your answer is x=7 and y=6.
