I have tried these problem cannot get the answer so could some one help me.
Solve by the subsitution method.
2x-7y=-11
2x +17=y
What is the solution of the system.

  • algebra -

    I have tried to work those problem all I ask is for your help

  • algebra -

    the second equation tells you exactly what y is
    y = 2x+17
    put that into the first:
    2x - 7(2x+17) = -11

    I am sure you can finish that.
    Once you have the x, sub that back into your
    y = 2x + 17
