Solve for y in the equation: 4y = 20.

Solve for y in the equation: 4y = 20.

• A. 2
• B. 4
• C. 5
• D. 6

Answer: (C)

To solve the equation \( 4y = 20 \), you want to isolate the variable \( y \). This can be accomplished by dividing both sides of the equation by 4, which is the coefficient of \( y \). When you divide both sides by 4, the equation becomes: \[ y = \frac{20}{4} \] Calculating the right side gives: \[ y = 5 \] Thus, the solution to the equation is \( y = 5 \). This makes option C the correct answer. Understanding this process is important because it highlights how you can manipulate equations to isolate a variable, which is a fundamental skill in algebra.

To solve the equation ( 4y = 20 ), you want to isolate the variable ( y ). This can be accomplished by dividing both sides of the equation by 4, which is the coefficient of ( y ).

When you divide both sides by 4, the equation becomes:

[

y = \frac{20}{4}

]

Calculating the right side gives:

[

y = 5
