    Answer:

    (4, 1)

    Step-by-step explanation:

    since y=1/2x-1 in the first equation, you can substitute it into the second one:

    1/2x – 1 = -x + 5

    then add x to both sides:

    3/2x – 1 = 5

    then add 1 to both sides:

    3/2x = 6

    then divide both sides by the fraction to get:

    x=4

    then you substitute 4 into y=1/2x – 1

    y = 1/2(4)-1

    y = 1

    so your answer is x=4 and y=1
