solve for y.\n4(y - 1) = 20\ny = ?

Explanation:

Step1: Expand the left - hand side

$4(y - 1)=4y-4$, so the equation becomes $4y - 4=20$.

Step2: Add 4 to both sides

$4y-4 + 4=20 + 4$, which simplifies to $4y=24$.

Step3: Divide both sides by 4

$\frac{4y}{4}=\frac{24}{4}$, so $y = 6$.

Answer:

$6$
