Question

resolver para y.

c = 20 + y

Explanation:

Step1: Isolate y by subtracting 20.

To solve for \( y \) in the equation \( c = 20 + y \), we need to get \( y \) by itself. We can do this by subtracting 20 from both sides of the equation.
\[
c - 20 = 20 + y - 20
\]

Step2: Simplify the equation.

Simplifying the right - hand side, \( 20 - 20 = 0 \), so we are left with:
\[
y=c - 20
\]

Answer:

\( y = c - 20 \)
