What is the value of x in the equation 3x + 5 = 20?

Explanation:
To find the value of \( x \) in the equation \( 3x + 5 = 20 \), you first need to isolate \( x \). Start by subtracting 5 from both sides of the equation: \[ 3x + 5 - 5 = 20 - 5 \] This simplifies to: \[ 3x = 15 \] Next, divide both sides by 3 to solve for \( x \): \[ x = \frac{15}{3} \] This gives: \[ x = 5 \] This solution shows that the correct value of \( x \) is indeed 5, which is why the answer aligns with the proposed choice. Understanding this step-by-step process of isolating the variable is critical in solving linear equations effectively.

To find the value of ( x ) in the equation ( 3x + 5 = 20 ), you first need to isolate ( x ).

Start by subtracting 5 from both sides of the equation:

[ 3x + 5 - 5 = 20 - 5 ]

This simplifies to:

[ 3x = 15 ]

Next, divide both sides by 3 to solve for ( x ):

[ x = \frac{15}{3} ]

This gives:

[ x = 5 ]

This solution shows that the correct value of ( x ) is indeed 5, which is why the answer aligns with the proposed choice. Understanding this step-by-step process of isolating the variable is critical in solving linear equations effectively.
