What is the solution to the equation 3x + 5 = 20?

To find the solution to the equation 3x + 5 = 20, we follow these steps:

1. Subtract 5 from both sides of the equation to isolate the term containing x:

( 3x + 5 - 5 = 20 - 5 )

This simplifies to:

( 3x = 15 )

2. Now, divide both sides by 3 to solve for x:

( \frac{3x}{3} = \frac{15}{3} )

This results in:

( x = 5 )

The value x = 5 satisfies the original equation when substituted back in, since:

( 3(5) + 5 = 15 + 5 = 20 ).

This confirms that x = 5 is indeed the correct solution to the equation. Understanding the steps of isolating the variable and performing operations correctly is crucial in solving linear equations like this one.
