Question Simplify the expression: $3.2 - 9x + 7.1 - 3x$ .

Studdy Solution

STEP 1

Assumptions
1. We are given an algebraic expression $3.2 - 9x + 7.1 - 3x$ .
2. We need to simplify the expression by combining like terms.

STEP 2

Identify like terms in the expression. Like terms are terms that contain the same variable raised to the same power.
In the given expression, $-9x$ and $-3x$ are like terms because they both contain the variable $x$ raised to the first power.

STEP 3

Combine the like terms involving the variable $x$ by adding their coefficients.
The coefficients of $-9x$ and $-3x$ are $-9$ and $-3$ , respectively.
$-9 + (-3) = -9 - 3$

STEP 4

Calculate the sum of the coefficients.
$-9 - 3 = -12$

STEP 5

Combine the like terms involving the variable $x$ using the sum of their coefficients.
$-9x - 3x = -12x$

STEP 6

Now, identify the constant terms in the expression. Constant terms are terms without variables.
In the given expression, $3.2$ and $7.1$ are constant terms.

STEP 7

Combine the constant terms by adding their values.
$3.2 + 7.1$

STEP 8

Calculate the sum of the constant terms.
$3.2 + 7.1 = 10.3$

STEP 9

Combine the simplified like terms to write the final simplified expression.
$10.3 - 12x$
The simplified expression is $10.3 - 12x$ .
