If 5x + 3 = 18, what is the value of x?

If 5x + 3 = 18, what is the value of x?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

To find the value of \( x \) in the equation \( 5x + 3 = 18 \), we start by isolating \( x \). First, we need to eliminate the constant term on the left side of the equation. We do this by subtracting 3 from both sides: \[ 5x + 3 - 3 = 18 - 3 \] This simplifies to: \[ 5x = 15 \] Next, we solve for \( x \) by dividing both sides by 5: \[ x = \frac{15}{5} \] This simplifies to: \[ x = 3 \] Thus, the value of \( x \) is 3. This solution methodically follows algebraic principles, demonstrating how to isolate a variable in an equation. The correct answer of 3 aligns with our step-by-step breakdown, confirming that \( x = 3 \) is indeed the solution to the original equation \( 5x + 3 = 18 \).

To find the value of ( x ) in the equation ( 5x + 3 = 18 ), we start by isolating ( x ).

First, we need to eliminate the constant term on the left side of the equation. We do this by subtracting 3 from both sides:

[

5x + 3 - 3 = 18 - 3

]

This simplifies to:

[

5x = 15

]

Next, we solve for ( x ) by dividing both sides by 5:

[

x = \frac{15}{5}

]

This simplifies to:

[

x = 3

]

Thus, the value of ( x ) is 3. This solution methodically follows algebraic principles, demonstrating how to isolate a variable in an equation.

The correct answer of 3 aligns with our step-by-step breakdown, confirming that ( x = 3 ) is indeed the solution to the original equation ( 5x + 3 = 18 ).
