Solve for a: 9a - 3 = 24.

Solve for a: 9a - 3 = 24.

• A. 2
• B. 3
• C. 4
• D. 6

Answer: (B)

To solve the equation \( 9a - 3 = 24 \), the goal is to isolate the variable \( a \). Start by adding 3 to both sides of the equation to eliminate the constant on the left side: \[ 9a - 3 + 3 = 24 + 3 \] This simplifies to: \[ 9a = 27 \] Next, divide both sides by 9 to isolate \( a \): \[ a = \frac{27}{9} \] This simplifies further to: \[ a = 3 \] The correct answer is therefore 3. This means that if you substitute \( a \) back into the original equation, the left side will equal the right side, confirming that 3 is indeed the value of \( a \).

To solve the equation ( 9a - 3 = 24 ), the goal is to isolate the variable ( a ).

Start by adding 3 to both sides of the equation to eliminate the constant on the left side:

[

9a - 3 + 3 = 24 + 3

]

This simplifies to:

[

9a = 27

]

Next, divide both sides by 9 to isolate ( a ):

[

a = \frac{27}{9}

]

This simplifies further to:

[

a = 3

]

The correct answer is therefore 3. This means that if you substitute ( a ) back into the original equation, the left side will equal the right side, confirming that 3 is indeed the value of ( a ).
