How do I simplify this expression? 2x+7+3x

gather the x terms

5x+7

So for this one..

2x+9y+6x
It'd be 8x+9y?

Right.

:) Thank you

To simplify the expression 2x + 7 + 3x, you can combine like terms. Like terms have the same variable raised to the same power. In this case, both terms have the variable x raised to the power of 1.

To combine the like terms, add the coefficients (the numbers in front of the x) together and keep the variable x.

So, 2x + 7 + 3x becomes (2 + 3)x + 7.

Adding the coefficients gives us 5x + 7. Therefore, the simplified expression is 5x + 7.
