Question

a. 4y + 3 = 19

Explanation:

Step1: Subtract 3 from both sides

To isolate the term with \( y \), we subtract 3 from both sides of the equation \( 4y + 3 = 19 \). This gives us \( 4y + 3 - 3 = 19 - 3 \), which simplifies to \( 4y = 16 \).

Step2: Divide both sides by 4

To solve for \( y \), we divide both sides of the equation \( 4y = 16 \) by 4. So, \( \frac{4y}{4} = \frac{16}{4} \), which simplifies to \( y = 4 \).

Answer:

\( y = 4 \)
