Which expression is simplified correctly?: 5x + 2x - 3x?

• A. 4x
• B. 6x
• C. 3x
• D. 5x

Answer: (A)

The expression 5x + 2x - 3x can be simplified correctly by combining the like terms, which are all terms involving 'x'. To do this, you first add the coefficients of 'x': - Start with the first term, which is 5x. - Add the second term, 2x, to it: 5 + 2 = 7. - Then subtract the third term, 3x, from this total: 7 - 3 = 4. Putting it all together, you get 4x. This shows that the expression has been simplified correctly to 4x by following the process of combining the coefficients of the like terms. Each coefficient corresponds to the number of 'x' terms present, leading to the resulting simplified expression.

The expression 5x + 2x - 3x can be simplified correctly by combining the like terms, which are all terms involving 'x'. To do this, you first add the coefficients of 'x':

• Start with the first term, which is 5x.

• Add the second term, 2x, to it: 5 + 2 = 7.

• Then subtract the third term, 3x, from this total: 7 - 3 = 4.

Putting it all together, you get 4x. This shows that the expression has been simplified correctly to 4x by following the process of combining the coefficients of the like terms. Each coefficient corresponds to the number of 'x' terms present, leading to the resulting simplified expression.
