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
