Question

1.5 module 1 post-test

simplify:

(3x - 7 + 2x - 4)

(5x - 11)
(5x - 3)
(x - 3)
(6x + 11)

Explanation:

Identify the terms in the expression

We begin with the given algebraic expression:

$$ 3x - 7 + 2x - 4 $$

We identify the variable terms containing \(x\) and the constant terms.

Group the like terms

Using the Linear Equations knowledge point

$$ (3x + 2x) + (-7 - 4) $$

Combine the variable terms and constant terms

Using the Linear Equations knowledge point

$$

Combining these results gives:

$$ 5x - 11 $$

Answer:

• (A) \(5x - 11\) (Correct answer)
• (B) \(5x - 3\)
• (C) \(x - 3\)
• (D) \(6x + 11\)
