Simplify the expression by combining like terms.

7x-3+2x+6

To simplify the expression, we need to combine like terms.

The like terms in the expression are 7x and 2x, which can be combined to 9x.

The constant terms in the expression are -3 and 6, which can be combined to 3.

Therefore, the simplified expression is 9x + 3.

To simplify the expression by combining like terms, we need to combine the terms that have the same variable.

In this expression, we have terms with the variable 'x'. We can combine the '7x' term and the '2x' term.

So the expression can be simplified as follows:

7x + 2x - 3 + 6

Now, let's add the coefficients of the 'x' terms:

(7 + 2)x - 3 + 6

Simplifying the coefficients, we have:

9x - 3 + 6

Next, we can combine the constant terms:

9x + 3

Therefore, the simplified expression is:

9x + 3

Simplify by using the distributive property.

-3 (2x-4)

To simplify the expression by combining like terms, we can add the coefficients of the terms that have the same variable.

The given expression is 7x - 3 + 2x + 6.

Combining the like terms, we add the coefficients of the x terms:

(7x + 2x) - 3 + 6

Simplifying further, we get:

9x - 3 + 6

Finally, combining the constants, we get:

9x + 3

To simplify the expression, we can use the distributive property.

Start by multiplying -3 by each term inside the parentheses:

-3 * 2x = -6x

-3 * -4 = 12

Therefore, the expression -3 (2x-4) simplifies to:

-6x + 12
