    Answer:

    Subsitution

    Step-by-step explanation:

    We have the equations:

    x=2y-1

    3x+y=11

    The 3 methods of solving systems of equations are:

    graphing

    substitution

    addition/elimination

    Graphing involves graphing the two equations and finding their point of intersection, which is the answer

    Substitution involves isolating one of the variables in one of the equations, then substituting the resulting expression into the other equation to find both numbers

    Addition/Elimination involves adding the two equations together to clear a variable, solving for the other variable, and substituting the answer to the first variable in one of the equations to find the value of the cleared variable from before

    Since we have x already isolated onto one side in the first expression, we can easily substitute it as 2y-1 in the second equation.

    Therefore, substitution is the best method to solve this graph.

    hope this helps!
