What is the value of x in the equation: 7x + 14 = 35?

To find the value of ( x ) in the equation ( 7x + 14 = 35 ), we can follow these steps:

1. Start by isolating the term with ( x ). To do this, subtract 14 from both sides of the equation:

[

7x + 14 - 14 = 35 - 14

]

This simplifies to:

[

7x = 21

]

2. Next, divide both sides by 7 to solve for ( x ):

[

x = \frac{21}{7}

]

This leads us to:

[

x = 3

]

Thus, the value of ( x ) is 3, which corresponds to the option labeled as B.

The answer of 4 indicated is not appropriate since substituting ( x = 4 ) back into the original equation would yield ( 7(4) + 14 = 28 + 14 = 42 ), which does not equal 35. The correct process leads to the conclusion that ( x = 3 ) is the valid solution.
