Studdy Solution

STEP 1

Assumptions1. The algebraic expression is $-3x +9x$ . . We are asked to simplify the expression by combining like terms. In this case, the like terms are the terms that have the same variable part, which is $x$ .

STEP 2

We can combine like terms by adding or subtracting the coefficients (the numbers in front of the variables). Here, the coefficients are $-$ and $9$ .
$-x +9x$

STEP 3

Add the coefficients $-3$ and $9$ .
$(-3 +9)x$

STEP 4

Calculate the sum of $-3$ and $9$ .
$6x$ The simplified expression is $6x$ .
