    Answer:

    Step-by-step explanation:Simplifying

    0 = 2.5y + -20

    Reorder the terms:

    0 = -20 + 2.5y

    Solving

    0 = -20 + 2.5y

    Solving for variable ‘y’.

    Move all terms containing y to the left, all other terms to the right.

    Add ‘-2.5y’ to each side of the equation.

    0 + -2.5y = -20 + 2.5y + -2.5y

    Remove the zero:

    -2.5y = -20 + 2.5y + -2.5y

    Combine like terms: 2.5y + -2.5y = 0.0

    -2.5y = -20 + 0.0

    -2.5y = -20

    Divide each side by ‘-2.5’.

    y = 8

    Simplifying

    y = 8

    SO the answer is y=8 I think srry if i get it wrong
