Select the correct expressions.
Identify the equivalent expressions of 4(2x + x – 3) – 3x + 3.

Answer 1

Explanation:

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

8x + 4x - 12 - 3x + 3

9x - 9

9x/9x 9/9x

x - 1

Answer 2

4(3x - 3) + 3 - 3x, 9x - 9, and 9(x - 1) are all equivalent expressions.

Explanation:

first we simplify 4(2x + x – 3) – 3x + 3.

1. combine like terms: 4(3x - 3) + 3 - 3x

if you use the commutative property for the numbers outside the parenthesis you can already see that 4(3x - 3) + 3 - 3x is equivalent.

2. distributive property: 12x - 12 + 3 - 3x

3. combine like terms again: 9x - 9

this shows that 9x - 9 is another equivalent expression.

then 9(x-1) is literally just 9x - 9 factored so yea
