pls help me to solved this equation
1. 6y=x+18
2y-x=6,
2. 4x=3y=13
2x-4y=1
3. y=3x-12
2/3x=2/3-1/6y pls help me now. this equation is Systems of Linear Equations Solved Algebraically.

  • math -

    1. x=18-6y
    2y-6=x

    therefore, 18-6y = 2y-6
    18+6=2y+6y
    24=8y
    y=3

    x= 18-6y
    18-(6x3)
    x=0

    Do the rest by your own.
