Question

solve the literal equation for y. 2x - 4y = 20 y = \square

Explanation:

Step1: Isolate the term with y

Subtract \(2x\) from both sides of the equation \(2x - 4y = 20\).
We get \(-4y = 20 - 2x\).

Step2: Solve for y

Divide each term in \(-4y = 20 - 2x\) by \(-4\).
\(y=\frac{20}{-4}-\frac{2x}{-4}\)
Simplify each term: \(\frac{20}{-4}=-5\) and \(\frac{-2x}{-4}=\frac{x}{2}\)
So \(y = \frac{x}{2}-5\)

Answer:

\(\frac{1}{2}x - 5\) (or \(\frac{x}{2}-5\))
