What is the simplified form of \( 3x + 4x \)?

Explanation:
To simplify the expression \( 3x + 4x \), you combine the like terms. Both terms, \( 3x \) and \( 4x \), share the common variable \( x \). To combine these expressions, you add the coefficients (the numbers in front of the variables). So you take \( 3 \) (from \( 3x \)) and add \( 4 \) (from \( 4x \)), resulting in: \[ 3 + 4 = 7 \] Thus, when you write the combined terms, you have \( 7x \). In conclusion, the simplified form of \( 3x + 4x \) is \( 7x \).

To simplify the expression ( 3x + 4x ), you combine the like terms. Both terms, ( 3x ) and ( 4x ), share the common variable ( x ).

To combine these expressions, you add the coefficients (the numbers in front of the variables). So you take ( 3 ) (from ( 3x )) and add ( 4 ) (from ( 4x )), resulting in:

[

3 + 4 = 7

Thus, when you write the combined terms, you have ( 7x ).

In conclusion, the simplified form of ( 3x + 4x ) is ( 7x ).
