    2y+10+3y+15 = 180

    5y + 25=180

    5y =180-25

    5y = 155

    y= 155/5

    y= 31

    so the value of y =31

    (2y+10) = 2*31+10= 72

    (3y+15) = 3*31+ 15 = 108

    hope you like the answer pls mark my answer brainlist if u like it..

    take care.

    Answer:

    y=31

    Step-by-step explanation:

    supplementary angles sum to 180 degree

    2y + 10 + 3y + 15 = 180

    5y + 25 = 180

    5y = 180 – 25

    5y = 155

    y = 155/5

    y = 31
