Question

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

Answer 1

5x-4

add like terms and simplify

Answer 2

5x - 4

Explanation:

First, expand the terms in parenthesis by multiplying each term within the parenthesis by the term outside the parenthesis:

2(x+4) + 3(x−4)

(2 × x)+(2 × 4)+(3 × x)−(3 × 4)

2x + 8 + 3x − 12

Next, group like terms:

2x + 3x + 8 - 12

Now, combine like terms:

(2 + 3)x + (8 - 12)

5x + ( − 4 )

5x - 4

Hope this helps! :)
