    Answer:

    (2,1)

    Step-by-step explanation:

    -3x + 7 = -2x + 5

    x = 2

    y = -6 + 7

    y = 1

    Answer:

    (2,1)

    Step-by-step explanation:

    Remark

    One thing you need to remind yourself of: The y value in both equations must be the same.

    That means that the two right hand values are

    -3x + 7 = – 2x + 5         Subtract 5 from both sides.

          -5              -5

    -3x + 2 = – 2x               Add 3x to both sides

    +3x          +3x

           2 = x

    Now use one of the equations to solve for y

    y = -2x + 5

    y = -2(2) + 5

    y = – 4 + 5

    y = 1

    We should check this by graphing it. Notice the two graphs do cross at (2,1) just as predicted.
