Question

atch the equivalent expressions.
$3x + 3x + 7$
$2 + 3x$
$x + x + 1 + 1$
$2x + 2$
$6x + 7$
$3x + 2$

Explanation:

Step1: Simplify \(3x + 3x + 7\)

Combine like terms: \(3x+3x = 6x\), so \(3x + 3x + 7=6x + 7\).

Step2: Simplify \(2 + 3x\)

Rearrange the terms: \(2 + 3x=3x + 2\).

Step3: Simplify \(x + x + 1 + 1\)

Combine like terms: \(x+x = 2x\) and \(1 + 1=2\), so \(x + x + 1 + 1=2x + 2\).

Answer:

• \(3x + 3x + 7\) matches \(6x + 7\)
• \(2 + 3x\) matches \(3x + 2\)
• \(x + x + 1 + 1\) matches \(2x + 2\)
