What is the solution to the equation y - 4 = 20?

What is the solution to the equation y - 4 = 20?

• A. 20
• B. 28
• C. 24
• D. 16

Answer: (C)

To find the solution to the equation \( y - 4 = 20 \), the goal is to solve for \( y \). To isolate \( y \), you need to eliminate the constant on the left side of the equation. This can be accomplished by adding 4 to both sides. Here's how it works step-by-step: 1. Start with the equation: \( y - 4 = 20 \) 2. Add 4 to both sides: \( y - 4 + 4 = 20 + 4 \) 3. Simplify the equation: \( y = 24 \) Thus, the solution to the equation is \( y = 24 \). Choosing 24 means that when substituted back into the original equation, it satisfies the condition \( y - 4 \) equals 20, since \( 24 - 4 = 20 \) confirms that our solution is accurate.

To find the solution to the equation ( y - 4 = 20 ), the goal is to solve for ( y ).

To isolate ( y ), you need to eliminate the constant on the left side of the equation. This can be accomplished by adding 4 to both sides.

Here's how it works step-by-step:

1. Start with the equation:

( y - 4 = 20 )

2. Add 4 to both sides:

( y - 4 + 4 = 20 + 4 )

3. Simplify the equation:

( y = 24 )

Thus, the solution to the equation is ( y = 24 ).

Choosing 24 means that when substituted back into the original equation, it satisfies the condition ( y - 4 ) equals 20, since ( 24 - 4 = 20 ) confirms that our solution is accurate.
