Simplify the expression by combining like terms. 7x-3+2x+6

Combining like terms, the expression 7x-3+2x+6 becomes 9x+3.

To simplify the expression 7x - 3 + 2x + 6, we need to combine the like terms.

The two terms with 'x' are 7x and 2x.
Adding them together, we get 7x + 2x = 9x.

Now let's combine the constants -3 and 6.
-3 + 6 = 3.

Therefore, the simplified expression is 9x + 3.

To simplify the expression, you need to combine the like terms. Like terms have the same variable(s) raised to the same exponent(s).

The expression is:

7x - 3 + 2x + 6

First, combine the x terms (7x and 2x):

7x + 2x = (7 + 2)x = 9x

The expression becomes:

9x - 3 + 6

Now combine the constant terms (-3 and 6):

-3 + 6 = 3

The simplified expression is:

9x + 3
