Solve the equation.<br> 2.5 = 0 - (-20)<br> 0-17.5<br> 0-22.5<br> O 22.5<br> 0 17.5
Nikolay [14]

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
