Answer:

Hope this helps (answers in bold)

Step-by-step explanation:

( i )3x-1 = 2(x + 1)

    3x - 1 = 2x + 2

    3x - 2x = 2 + 1

    x = 3

    5y + 1 = 6y - 1

    5y - 6y = -1 -1

    -y = -2

    y = 2

( ii )x + 40 + 90 = 180 (angle sum property)

    x = 180 - 130

    x = 50degree

   

    y = 40degree (alternate interior angle)
